 In 2008, five rowers drowned and a single rower drowned in 2009 during the boat races.The celebration turned tragic in 2010, when thousands became trapped and stampeded off the bridge between Phnom Penh and Diamond Island, killing 351 people and injuring 395 more.Rumors spread that it was caused by fear of a coming storm or electrical shock from faulty wiring, and authorities ultimately laid blame on the swaying of the bridge.
