ROME — Italian prosecutors say eight people are under investigation so far in connection to a stampede at a packed nightclub that killed six people, five of them teenagers.Authorities stressed on Monday that the investigation of the stampede early Saturday was just beginning. They said they want to know about the security measures and capacity of the Blue Lantern disco in the small town of Corinaldo, as well as the panic that sent concertgoers running for the exits.One hypothesis is that would-be thieves used irritant sprays on the crowd to hide thefts, which has been done at other concerts and gatherings in Italy.The seven adults under investigation include the club owners and concert organizers. Prosecutors say a 17-year-old was added to the list because three witnesses “generically” identified him.The Associated Press
NEW DELHI: Delhi Jal Board (DJB) has urged the Delhi high court here that the Centre be asked to supervise water supply from Haryana to the national Capital, saying any reduction in Wazirabad reservoir water level would hit important areas where residences of President, Prime Minister and judges are located. Citing the coming lean season, the DJB has contended that “an imminent water crisis is likely to hit the New Delhi area in the next few weeks owing to the failure of state of Haryana to supply water as required pursuant to orders of the Supreme Court”. Also Read – After eight years, businessman arrested for kidnap & murderThe Board has contended the issue of water supply assumes importance in the 100 days long lean season till the arrival of monsoon and Haryana sought to strictly comply with the Supreme Court’s direction to keep the Wazirabad reservoir full during this period. In its affidavit placed on record before a bench of Chief Justice Rajendra Menon and Justice A J Bhambhani, the DJB has contended that the neighbouring state was “showing reluctance” in supplying the minimum required 120 Also Read – Two brothers held for snatchingscusec of water to keep the Wazirabad reservoir full at all times, which amounts to disobedience of judicial orders. “As an interim measure, at least for the coming lean season of about 100 days, central government supervision be requested in the matter,” it has said in the affidavit. The DJB has claimed that Haryana has about 22,000 cusecs of water available to it from all sources, but still it was reluctant to supply the 120 cusecs required to keep the Wazirabad reservoir full at all times during the lean season till the end of June or till monsoon arrives. A cusec is a unit of flow of water equal to one cubic foot per second. The board has claimed that any reduction in the Wazirabad reservoir’s water level would hit the supply to the capital’s most important and sensitive areas where residences of the President,Prime Minister and judges as well as various government departments are located. It has urged the court to ask the central government to intervene and ensure that Haryana keeps up the water supply as ordered by the apex court.
The recommendations by the Commission on Effective Development Cooperation with Africa include creating an African Guarantee Fund in partnership with the African Development Bank, ensuring access to energy, and unleashing the power of African entrepreneurship.Mr. Ban called the recommendations “far-reaching,” adding that if implemented conscientiously, such steps will help mitigate the effects of the economic crisis and help to lift millions of people out of poverty.Speaking at the presentation of the report in New York, the Secretary-General warned that the gains made by African countries over the past decade are being threatened by climate change, armed conflict, political upheaval and crises involving food, fuel and the global economy.“Investments are declining, businesses are struggling to survive and jobs are being lost,” he said. “Africa and its development partners must act urgently to promote stability, prosperity and peace.”He welcomed the report’s emphasis on youth employment and opportunities for young people, noting that recent figures show that more than 60 per cent of those unemployed in sub-Saharan Africa are below the age of 24. “This terrible waste of human resources is visible on the streets of the continent’s cities. Africa needs its young people to get to work on its behalf,” said Mr. Ban. He called on Africa’s leaders to show the “bold leadership” required to intensify the fight against poverty, while urging the donor community to help implement the report’s recommendations, including through financial and technical aid. The UN will continue to be Africa’s “close and enduring partner” in this important effort, he added.Launched in 2008 by Danish Prime Minister Lars Løkke Rasmussen, the Commission comprises heads of State and government, politicians, experts, representatives from international and regional organisations, as well as the business community, civil society and the academic world. 23 November 2009Secretary-General Ban Ki-moon today lauded a new report which outlines steps to be taken by Africa and its development partners to help lift millions of people across the continent out of poverty.

After the leak occurred, however, and plunging pressure in the pipeline triggered an alarm, it wasn’t shut down for more than 30 minutes.Plains wouldn’t comment on the report because of ongoing investigations of the spill, a spokeswoman said. Local, state and federal prosecutors are probing the spill and regulators could issue fines against the Texas-based company.Reports of corrosion of the underground pipe and pump problems were previously disclosed, but regulators hadn’t labeled corrosion as the root cause of the leak, pinpointed the precise moment the pipe failed or provided a timeline of how long it took to shut down the pipe.The spill two weeks before the popular Memorial Day weekend forced the state to close popular beaches as the oil fouled a pristine stretch of coastline and an oil sheen spread over miles of the Pacific Ocean. More than 300 dead animals, including pelicans and sea lions, were recovered after the spill that sent tar balls drifting more than 100 miles away to Los Angeles beaches.The report said the leak in Line 901 happened after a pump unintentionally shut down at the pumping station on nearby Line 903 while a technician was removing a non-working pump.Pressure increased in Line 901 and its pump was stopped remotely from the company’s control room in Midland, Texas.The leak happened just before 11 a.m., about two-to-three minutes after the pump was restarted. Pressure jumped to 721 pounds per square inch — from the 677 psi it had been operating at before the shutdown.About two minutes later, pressure dropped below 200 psi and a low-pressure alarm was triggered in the control room. An oil company that wanted to pump oil through the pipeline reported to the controller that there wasn’t enough pressure in pipeline to deliver its product.The pump on Line 903 exceeded a high temperature limit and then shutdown. The controller tried to restart it several times, but didn’t shut off the pump on Line 901 until about 11:30 a.m.A pipeline leak monitoring system had been turned off at the control centre, the report said, though it noted that was still under investigation.Richard Kuprewicz, a pipeline safety expert, said there could be a good reason for it being off, but it’s potentially significant.“‘Turned off’ is the magic word,” Kuprewicz said. “Why this was turned off would be a valid question.”The agency said it would provide more details when it issues a final report this spring.Kuprewicz said it struck him that the pipe failed when it was only pumping at about 50 per cent of its maximum operating pressure. That indicated to him that there were problems on the pipeline.A chart in the report showed corrosion anomalies grew and intensified between surveys in 2007, 2012 and the last tests just weeks before the leak.Robert Bea, an engineering professor at University of California, Berkeley, questioned how Plains could operate in a sensitive environmental area — through scenic hills and near the beautiful coast — with “severely corroded” pipeline.“I think the answer to this question will show that the root causes of this accident are firmly rooted in organizational malfunctions that resulted in underestimates of the likelihoods and consequences of a breach in Line 901,” Bea wrote in an email.The report also noted that the spill, originally estimated at up to 100,000 gallons, had dumped 142,800 gallons.

Soilworks, a leader in dust control and soil stabilisation technology, is relocating its world headquarters to Scottsdale, Arizona. It says the new location will help the company focus its energies more on its core business areas such as mining. “This is a natural progression for our company and one that we’re excited to make,” said Chad Falkenberg, founder of Soilworks.”It caps off one of the best years our company has ever had.” Falkenberg said the company’s production facility, which is home to its large-scale heavy industrial production plant, construction facility, equipment yard, warehouse and 26-car rail-spur, will remain in Chandler.“For us, the move to Scottsdale allows us to be more centrally located for clients, employees and future expansion,” he said.It’s been an eventful year for Soilworks, which saw itself become the only company to have a synthetic copolymer pass the rigorous standards of the highly coveted and prestigious Certificate of Conformity from BNQ for its eco-friendly formula. The certification for Soiltac, the flagship product in Soilworks’ dust control and soil stabilisation suite of products, joined the company’s other key product, Durasoil, as the industry’s only suite of non-corrosive, eco-friendly and highly effective dust control products to pass BNQ.“It was further proof of the strict standards that we hold ourselves to every day,” Falkenberg said of the BNQ certifications for Soiltac and Durasoil. “Our mission is to always ensure that our customers receive the best products available on the market. These certifications demonstrated that.”Certification by BNQ is an exacting process that requires complete transparency and top-tier products that can hold up to rigid testing protocols. Last year, Durasoil became the first synthetic fluid dust suppressant ever to be awarded the highly coveted BNQ certification for its superior eco-friendly formula.The company also launched a re-designed website in 2014. According to Falkenberg, the new website allows for a more transparent and informative way to approach the dust control industry, with great care taken by the Soilworks team to ensure that all relevant information was included in the site. Since the company has always strived to produce the highest quality, best performing dust control products on the market, it was important that the new website also reflect that mission, Falkenberg said. “We want our customers to access our content in the most intuitive way possible, each time they visit the website,” he said.Soilworks provides engineered solutions to meet the broad needs of the dust control and soil stabilisation industry. Soilworks’ performance-driven portfolio of industry-leading products include Soiltac®, Powdered Soiltac®, Gorilla-Snot® and Durasoil®.

Aug 30 • iRobot Roomba S9 Plus vs. Neato Botvac D7 Connected At the very least, the Instant Vortex still includes enough modes to be versatile. The $119 price is also reasonable, though our favorite Simple Chef model from a year ago is just $60 on Amazon right now. Part of our hesitation with air fryers was how poorly they stacked up to an actual Instant Pot. It’ll be interesting to see if the makers of the popular gadget can do better where the others faltered. null Chris Monroe/CNET The newest kitchen gadget from the makers of the Instant Pot has an impressive seven cooking modes designed to serve up meals like a rotisserie chicken, as well as snacks like mozzarella sticks and french fries. The Instant Vortex Plus is an air fryer with a sizable capacity. In addition to the usual options, the Vortex includes extra presets like a dehydrate option for homemade jerky.The Instant Vortex Plus launched on Monday at Walmart. You can buy it now for $119. According to Instant Brands, the Vortex will roll out to other major retailers within the next couple of weeks. It holds 10 quarts of food. While it’s primarily an air fryer, six other cooking presets mean it can roast, broil, bake, reheat and dehydrate, plus there’s an option to rotate the included rotisserie spit. “We’re really excited to deliver a new product that gives our consumers the amazing deep fried taste without compromise,” said Katie Whiting, Instant Brands Marketing Director in a statement emailed to CNET. “They can create healthier versions of their favorite dishes and do so in a fast, easy and convenient way.”The Instant Pot pressure cooker gained popularity thanks to its versatility. The different cooking modes let you whip up a wide variety of delicious meals. When we tested air fryers last year, we found them to be more limited. They’re functionally just convection ovens shrunk down for your countertop, but the more focused heat of the smaller body supposedly makes them perfect for snack foods. We did have some tasty pizza rolls during testing, but still found it hard to get excited about any model.

A constable of Special Security and Protection Battalion (SPBn), stationed at the Ganabhaban (prime minister’s official residence), sustained bullet injuries mistakenly early Monday.The injured policeman has been identified as Rahimuddin.SPBn-2 officials said that the victim was shot accidentally during the regular checking of firearms around 3:00am.He was rushed to the Dhaka Medical College Hospital and later transferred to the National Institute of Cardiovascular Diseases (NICVD) at Sher-e-Bangla Nagar, said DMCH police outpost sub-inspector Bachchu Mia.Selim Khan, the police superintendent of SPBn-2, said that Rahimuddin may require surgery.An investigation team has been formed to investigate the matter.
Catalan police officers ‘Mossos d’Esquadra’ try stop pro-referendum people from going into ‘Escola Collaso i Gil’ school on 29 September 2017 in Barcelona. Photo: AFPPolice in Catalonia had already sealed over half of the 2,315 polling stations in the region mid-Saturday to stop an independence referendum from taking place, the Spanish government said, as separatists remained determined to fight for their right to vote.Teachers, parents, students and activists in this wealthy northeastern region have leapt into action to defend the vote slated for Sunday, defying Madrid’s warnings of repercussions by occupying more than 160 schools designated as polling stations, it said.Enric Millo, the central government representative in Catalonia, told reporters 1,300 polling stations had already been sealed off.He said that 163 of those had already been occupied when they were sealed off, which meant those inside were allowed to leave but no one could go in.AFP reporters, however, visited several schools occupied by parents, students and locals where people could go in and out freely, indicating there may be more occupied buildings that have yet to be sealed off.The standoff between the central government and Catalan leaders over an independence referendum opposed by Madrid has morphed into one of the biggest crises to hit Spain since democracy was restored after the death of dictator Francisco Franco in 1975.As such, it has Spaniards the country over worried.In Spain’s major cities, Madrid, Barcelona, Sevilla, Santander, Alicante, Valencia and Malaga, thousands protested for Spanish unity.“We shouldn’t have got to this point. We’ve arrived at a point of no return,” said Fernando Cepeda, a 58-year-old engineer, a Spanish flag tied around his waist in front of Madrid’s city hall.Call to remain peacefulCatalan separatist leaders and organisers of “committees to protect the referendum” stressed that everyone must remain peaceful.In one incident, though, someone fired a pellet gun on Friday night at a group of people standing in front of an occupied high school in the Catalan town of Manlleu, lightly injuring three people, police said.The referendum has sown divisions among Catalans themselves, with the region deeply split on independence, even if a large majority want to be allowed to settle the matter in a legal vote.Authorities in Madrid have instructed police to ensure no votes are cast in a referendum that the courts have ruled unconstitutional.For days, they have been seizing electoral items such as ballot papers while prosecutors have ordered the closure of websites linked to the vote and the detention of key members of the team organising the referendum.But those for the vote have mobilised.On Friday, tractors paraded through Barcelona, some decked with the “Estelada”, the separatists’ flag of red-and-yellow stripes with a white star on a blue chevron.They and firefighters have pledged to protect polling stations.From district to district, people gathered to form “Committees to protect the referendum”, using the Telegram messaging app to get organised and urging everyone to remain peaceful, said an AFP correspondent who saw some of the messages.The move appeared to be partly coordinated by a platform of “schools open for the referendum.”Mobilisation will continueCarles Riera, a lawmaker in the regional parliament for the radical CUP party, part of Catalonia’s separatist coalition, vowed that mobilisation would continue after Sunday’s vote-if the “yes” camp won but Madrid opposed the result, as is almost certain.“We’re in a process of popular mobilisation that is going to last a while,” he told reporters.“This democratic wave, this level of auto-organisation will have to keep going for a long time to defend the republic.”On Friday, Spain’s education ministry said in a statement that head teachers in Catalonia “were not exempt from liability” if they cooperated and allowed their schools to remain open for the vote.Some schools have imagined innovative ways to circumvent an order that public spaces cannot be used for the referendum by organising leisure activities all over the weekend, from pyjama parties for the kids to volleyball games.Barcelona’s Joan Brossa high school, for instance, advertised a series of activities for Friday and Saturday, including film screenings, football matches and Zumba dance fitness classes.It remained unclear though how people would be able to enter sealed-off schools on Sunday to vote, even if they are occupied.The Mossos d’Esquadra Catalan police have warned about the risk of “disruption of public order” if efforts are made to prevent people from casting ballots.Madrid has sent thousands of extra police officers from other forces to Catalonia-which accounts for one fifth of Spain’s economy-to stop the referendum from happening.Catalan Vice-President Oriol Junqueras has said that there are alternatives for citizens to vote, without saying what they are.
Rise of the Tomb Raider was one of last year’s best and most acclaimed games. However, the title was exclusive to the Xbox One and Xbox 360, and many gamers missed out on it. That’s going to change at the end of the month, as the title will be available for PC via the Windows Store, Steam, and other outlets on January 28.Seeing as this is the PC release, it will have a number of features which are exclusive to the platform. The most noteworthy feature will be that the game will fully support eye-bleeding 4K resolution. This will also be the first game to include “cutting edge” VXAO technology, which was developed in conjunction with NVIDIA. You can see how nice this game will look on PCs below. The standard version of the game will retail for $60. A Digital Deluxe Edition, which comes with the Baba Yaga DLC, will sell for $90. There will also be a pretty awesome collector’s edition of the game that comes with all the content from the Digital Deluxe Edition, a 12-inch Lara Croft statue, replicas of Lara’s journal and jade necklace, and a steel case. This one will set you back $150.Below are the PC minimum requirements:OS: Windows 7 64bitProcessor: Intel Core i3-2100 or AMD equivalentGPU: NVIDIA GTX 650 2 GB or AMD HD7770 2 GBRAM: 6 GBHD Space: 25 GBDirectX: DirectX 11Input: Mouse + KeyboardThough Rise of the Tomb Raider had a rocky start, it seems that its fortunes are turning around. According to TechTimes, the game only sold 330,000 copies during its first week of release. However, Microsoft yesterday announced that Rise of the Tomb Raider, along with every other title in Xbox’s “Greatest Games Lineup,” sold over a million copies during the holidays.Rise of the Tomb Raider will be released for the PlayStation 4 during the 2016 holiday season.

Then, we send a short, very bright light pulse of a carefully tuned peak power (which to the single photon detector looks like a supernova, which can be visible by the naked eye in the day sky). This very bright pulse causes sufficient photocurrent to cross the detection threshold only in one of the four polarizer settings. In the other three polarizer settings, the polarizer partially blocks light, the photocurrent stays below the threshold and the detector remains blind. Thus, Eve classically controls exactly which of the four polarizations Alice and Bob register. Then she can fake any correlation she pleases.”Theoretically, Alice and Bob should be able to detect Eve’s interference, but only when all loopholes are closed. The two loopholes the researchers took advantage of here were the locality loophole and the detection loophole. In the locality loophole, measurement choices on both sides may not be independent, while in the detection loophole, nonclassical behavior can be attributed to shared randomness, rather than entanglement, between the two photons.The researchers performed three experiments in which they faked the violation of Bell’s inequalities by taking advantage of one or both of these loopholes. The implication – that all loopholes must be closed in order to ensure accurate results – is not new to physicists. However, the experiments underscore how ignoring these loopholes can directly compromise the security of quantum communication systems. While the researchers explain that implementing a countermeasure against these attacks would not be difficult, it should not be assumed that quantum systems are fully secure until all loopholes are closed.“In any kind of quantum cryptography or secure quantum communication, a determined attacker will employ all tricks possible, in principle, to cheat the honest parties,” Makarov said. “There we show that users cannot blindly trust their quantum devices unless they see that the devices perform the Bell test with all loopholes closed (i.e., both the locality loophole and the detection loophole).“For verifying the laws of Nature, the significance is subtler, it is more philosophical there. On the one hand, we have no reason to believe Nature cooperates against our tests in an evil way. On the other hand, until a loophole-free Bell test has actually been done, the principles of quantum mechanics are, strictly speaking, not proven true.” Quantum eavesdropper steals quantum keys Copyright 2011 PhysOrg.com. All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. Explore further (PhysOrg.com) — In quantum mechanics, Bell’s inequalities serve as a test of nonclassical behavior: if something (such as a light source) violates Bell’s inequalities, then it can be considered to involve quantum behavior. Ensuring the nonclassicality of a system is important for applications such as quantum cryptography, in which quantum entangled photons ensure the system’s security while non-entangled photons do not. Now in a new study, scientists have shown that they can violate Bell’s inequalities using classical light by taking advantage of two loopholes common in some experiments. This “fake violation” emphasizes the importance of closing all loopholes in Bell tests, even if the detection devices appear to be operating normally. Citation: Fake violations of Bell tests reinforce importance of closing loopholes (2011, November 8) retrieved 18 August 2019 from https://phys.org/news/2011-11-fake-violations-bell-importance-loopholes.html The researchers, led by Vadim Makarov of the Norwegian University of Science and Technology in Trondheim, Norway, and the University Graduate Center in Kjeller, Norway, along with Christian Kurtsiefer of the National University of Singapore, have published their study in a recent issue of Physical Review Letters.In a typical experimental Bell test, a light source produces a pair of photons, with one photon sent to Alice and one to Bob. Alice and Bob each have a polarizer that they can set to one of four states, and a photon can only enter a polarizer when it’s in the same state. After a photon enters the polarizer, a photon detector amplifies a single electron generated by the photon into a large electric current. When this electric current crosses a certain threshold, it reveals the presence of a photon and its polarization. If the photon pair is classical, it must obey local realism so that the measurement of one photon does not influence the polarization of the other photon. But if the photon pair is entangled, then the measurement of one photon will instantaneously affect the other photon’s polarization. By repeating the experiment, counting the simultaneous detections (coincidences), and comparing the number of coincidences to what is possible in classical theory, Alice and Bob can determine if the detected photon pairs are entangled.Many previous studies have investigated how an eavesdropper, Eve, might be able to compromise the security of Alice and Bob’s communication channel. In the current study, the scientists showed that Eve can send strong, classical light pulses, with a polarization of her choice, into both Alice and Bob’s photon detectors at the same time. This classical light produces photocurrents that are interpreted as photons. Therefore, Alice and Bob are unknowingly measuring classical light pulses, which means that some of the coincidences that they count are not due to quantum entanglement but to Eve’s manipulation. Makarov explained in more detail how this experiment works: More information: Ilja Gerhardt, et al. “Experimentally Faking the Violation of Bell’s Inequalities.” Physical Review Letters 107, 170404 (2011).

Looking to shed those extra kilos through dieting? You may be at a loss, as human bodies tend to compensate by sparing energy, limiting the number of calories that we burn and hence affect our weight loss regimen, researchers say. According to the study, a group of neurons – ‘agouti-related neuropeptide’ (AGRP) – in a brain region hypothalamus contributes to the caloric thermostat that regulates our weight, regulating how many calories we burn. When activated, these neurons make us hungry and drive us to eat, but when there is no food available, they tend to compensate for the reduction in calories. Also Read – Add new books to your shelf”Our findings suggest that AGRP in the brain coordinate appetite and energy expenditure, and can turn a switch on and off to burn or spare calories depending on what’s available in the environment,” said Clemence Blouet from the University of Cambridge in Britain. “When we eat less, our body compensates and burns fewer calories, which makes losing weight harder,” Blouet added. However, as soon as food becomes available and we start eating, the action of the AGRP neurons is interrupted and our energy expenditure goes back up again to normal levels.In the study, published in the journal eLife, the researchers identified a new mechanism through which the body adapts to low caloric intake and limits weight loss in mice. Using a genetic trick to switch the AGRP neurons ‘on’ and ‘off,’ they rapidly and reversibly manipulated the neurons’ activity in mice, a finding that could help in the design of improved therapies to help reduce overeating and obesity.
At best Nicaraguan President Daniel Ortega has some work to do improving communications with his embassy officials in Costa Rica. At worst, he was caught by the Costa Rican Foreign Ministry bending the truth over whether he was invited to attend a May 3 summit with U.S. President Barack Obama in Costa Rica.On Thursday, Ortega told members of the press he didn’t know if he’d attend the early May meeting of the Central American Integration System (SICA) in San José, because he wasn’t invited.“We can’t speculate,” he said about Obama’s visit, “because until now, we don’t have anything formal, nothing official,” Ortega told the Nicaraguan press on Thursday.But late Thursday night, Ortega was called out on his bluff by the Nicaragua Dispatch, a Granada-based English-language news site operated by journalist Tim Rogers.“Ortega, who routinely skips Central American summits hosted by Costa Rica, told Sandinista government media outlets yesterday afternoon that he can’t comment on whether or not he will attend the May 4 regional summit with Obama and his Central American counterparts because he was not officially invited by the Costa Rican government,” the Nicaragua Dispatch reported.“But if Ortega doesn’t have the official invite yet, it must be because people in his government are keeping it from him,” Rogers wrote.Prompted by a phone call from the Dispatch, Costa Rican Foreign Ministry spokesman Miguel Díaz on Friday issued a statement confirming Ortega had been invited via a formal letter sent to the Nicaraguan Embassy in Costa Rica on April 3. Díaz attached a copy of the letter, which was signed as received by Nicaraguan official Douglas Espinoza the same day.“The government of Costa Rica ratified today [Friday] that since April 3 it had distributed invitations to the heads of state of [SICA] to attend the Summit in San José with the President of the United States, Barack Obama,” the Costa Rican ministry statement said.Relations between Ortega and his Costa Rican colleague, President Laura Chinchilla, are tense because of an ongoing border spat near the Caribbean coast that started in October 2010.Chinchilla currently presides over SICA and will host the May 3-4 meeting with Obama and other Central American presidents.

Ground transportation companies, including Adobe Rent-a-Car and Europcar, told the newspaper they could not deliver or pick up passengers from the airport.Over 3,900 passengers were scheduled to leave Costa Rica on Tuesday, according to the Civil Aviation Administration.Despite the thick crowds of red-shirted fans and the special attention paid to the Sele’s Avianca flight, international flights took off without any trouble, Silvia Chávez, press coordinator for Aeris Holdings, the company that operates Juan Santamaría International Airport, told The Tico Times. Only two domestic flights were delayed because of the Sele’s arrival.American Airlines, Delta, United, and US Airways all confirmed to The Tico Times that they did not have trouble getting flights out. Several airlines said they had warned customers the previous day to arrive early to head off any traffic delays. None reported missing passengers. Facebook Comments On Tuesday, tourists found themselves stuck between thousands of Costa Rican football fans and their flights home.As Costa Ricans obsessively tracked the arrival of their national men’s team, La Sele, after its historic run at the 2014 World Cup – many rushing to Juan Santamaría International Airport to catch a glimpse of the players – thousands of visitors to Costa Rica were trying to reach the airport. The General Cañas Highway connecting the airport in Alajuela with the capital was closed for most of Tuesday afternoon to allow the Sele’s parade truck to reach La Sabana Park, in western San José, where the closing ceremony took place.
More than 100 Gbagbo loyalists have been charged domestically with crimes committed during violence that stemmed from November 2010 elections. The conflict originated when Gbagbo refused to leave office after losing to Ouattara. But international human rights groups have also accused pro-Ouattara forces of committing postelection atrocities, and no member of Ouattara’s administration or security force has been detained or credibly investigated.“How can you sit at the table and discuss with someone who has killed your mother and imprisoned your brother?” Guehoun said.Following the FPI’s decision not to participate in an April forum, Human Rights Watch accused the party of being interested in scoring political points at the expense of stability.“These preconditions not only expose the FPI political elite’s contempt for the thousands of victims of often heinous forms of political violence,” HRW said, “but also reinforce the perception that the party remains more interested in hardline politics than in helping end the root causes of the country’s grave human rights abuses.”Civil society activist Yacouba Doumbia said he believed the demands were symptomatic of a party in disarray. “We can say that the politicians have their own logic that we are not mastering, because this precondition is not reasonable,” he said, noting that Ouattara’s government has no control over the ICC. Associated PressABIDJAN, Ivory Coast (AP) – Each morning, briefcase in hand, Laurent Boblet takes two taxis and two minibuses to the headquarters of the Ivorian Popular Front, the party of Ivory Coast’s former strongman who is now facing international charges of crimes against humanity.The three-floor villa in Abidjan’s upscale Riviera 2 neighborhood was once a hub of political activity and in 2010 was in full election mode: televisions blared, grounds were swarmed by campaign staffers, and party leaders stopped by daily. Nearly two years later _ following Laurent Gbagbo’s defeat to current President Alassane Ouattara, months of postelection violence that claimed 3,000 lives and Gbagbo’s eventual arrest _the villa is bare, its rooms empty save for plastic chairs, the occasional table and exposed wires marking where computers have been ripped from the walls. He agreed with FPI leaders that both sides should be investigated for postelection crimes, but also called on the ICC process to be respected.Boblet, an FPI supporter since its founding in 1982, said he still believes Gbagbo is the right person to lead the country. “It’s because Gbagbo said he was entering politics to become a representative of the poor,” Boblet said while tidying the party villa’s main gathering hall. “Since he is from a relatively poor family, I believe he is the right person to be this type of representative.”He denied being discouraged by challenges facing the FPI. The party boycotted legislative elections last December, and in a report released soon afterward the International Crisis Group described it as “torn between moderates and radicals and also geographically dispersed,” with some leaders in exile in Ghana, Togo, Benin and elsewhere.“It’s a simple matter of conviction. The fact that we’re still working will encourage other members that are hesitating to come mobilize for the party,” Boblet said. “The life of the party does not stop because we are disorganized and some leaders are in exile or in prison.” More Valley freeways to be closed this weekend for improvements Clean energy: Why it matters for Arizona As he spoke, other workers sat behind a plastic table selling various items bearing the former president’s image. T-shirts were available starting at about $4, while large towels were going for $15. Large signs featuring Gbagbo and other FPI figures decorated the compound. One near the entrance shows two photos of the former president and displays a phrase he uttered at his first ICC appearance last December: “We will go on to the end.”(Copyright 2012 The Associated Press.

Top Stories New high school in Mesa lets students pick career paths Think Tank analyzes the second round of Democratic debates The party, known by its French acronym of FPI, is now a mere trace of the force that dominated Ivorian politics for a decade. Gbagbo, who once had an office and resting quarters on the villa’s top floor, is being held at the International Criminal Court in The Hague on four counts of crimes against humanity. His wife, Simone, who Boblet remembers would regularly stop by to assess the campaign’s progress, has been detained by local authorities in the northern town of Odienne.Still, Boblet and three or four other staffers show up to the headquarters every day, keeping it presentable for party officials while hoping the former president will be set free.“For sustainable peace, I need to have my brother by me because he has some ideas to get peace in this country,” Boblet said, referring to Gbagbo. “He needs to be here to contribute to the development of the country.”This has increasingly become the FPI’s defining position as it struggles to maintain the influence it once did.In April, top FPI officials declined to participate actively in a gathering of political parties, making engagement with the government conditional on the release of Gbagbo and other detained FPI leaders. Though the FPI attended a meeting with the prime minister last week, spokesman Augustin Geuhoun said the party would continue to press for the release of its leaders.
