Qatar battles overcrowding at fan zone the day before FIFA World Cup kicks offAuthorities turned away thousands from packed concert in capital DohaAuthorities turned away thousands of fans on Saturday night from a concert celebrating the World Cup beginning the next day in Qatar, revealing the challenges ahead for Doha as it tries to manage crowds in FIFA's most compact tournament ever.Outside the venue, Qatari police, security guards and others guided the thousands away with giant foam fingers, bullhorns and blinking traffic control wands.And with Qatar deciding only Friday to ban beer sales from tournament stadiums, fan zones like the one on the seaside corniche hosting the concert will be the only FIFA-associated area serving pints — meaning more fans could wind up there."We know that what the police say here goes," said a 30-year-old trucker from Mumbai, who declined to give his name for fear of reprisals.Qatar's Supreme Committee for Delivery and Legacy, which oversees the World Cup, did not immediately respond to questions about the fan zone turning away crowds Saturday night."
