Thousands of Cambodians celebrating a water festival by the river in the Cambodian capital stampeded Monday night, killing hundreds. Cambodian Prime Minister Hun Sen says at least 339 people have been killed in a stampede at a festival in the capital, Phnom Penh. Â Most of the victims were crushed or drowned during a panic Monday as a huge crowd rushed to cross a bridge over the Tonle Sap river. The prime minister said more than 300 people were injured in the chaos, which he described as the "biggest tragedy" to strike the country since the communist Khmer Rouge ruled in a reign of terror in the 1970s. It remains unclear what caused the crowd to rush from a small island where hundreds had gathered to watch a traditional boat race. Panic escalated as crowds rushed to cross the bridge, causing people to fall into the river. Authorities estimate more than 1 million people had flocked to the capital for the annual water festival.
