During the Cambodian water festival, a stampede in Koh Pich, Phnom Penh, kills 347 people.

Bon Om Touk, also known as the Cambodian Water Festival, is celebrated in late October or early November, often corresponding with the lunar Mid-Autumn Festival. It marks the end of the monsoon season. The festivities are accompanied by dragon boat races, similar to those seen in the Lao Boun Suang Huea festival.

The Phnom Penh crowd crush occurred on 22 November 2010 when 347 people were killed and another 755 injured during a crowd crush at the Water Festival celebrations on the Diamond Gate Bridge of Diamond Island, in Cambodia.

Koh Pich, or "Diamond Island" in English, is a central business district in Phnom Penh, capital of Cambodia. Koh Pich faces the Boeng Keng Kang I district and is surrounded by the Mekong and Bassac rivers.

Phnom Penh is the capital and most populous city of Cambodia. It has been the national capital since 1865 and has grown to become the nation's primate city and its political, economic, industrial, and cultural centre. The city's name derives from Wat Phnom, a Buddhist temple, and Lady Penh, the city's founder. It sits at the confluence of the Tonlé Sap and Mekong rivers, and is the start of the Bassac River. It is also the seat of Cambodia's monarchy, based at the Royal Palace.

November 22 is the 326th day of the year in the Gregorian calendar; 39 days remain until the end of the year.
