At least 375 people have been killed in a stampede during a concert in the capital of Cambodia. Huge crowds had gathered on a small island for the final day of the Water Festival, one of the country's largest public events. Most of the victims were crushed, while others drowned trying to flee an overcrowded bridge. The Cambodian Prime Minister called it the nation's biggest tragedy since the Khmer Rouge mass killings of the 1970s.
