The dam forming Situ Gintung, an artificial lake in Indonesia, fails, killing at least 99 people.

Situ Gintung (Sundanese, Lake Gintung) is an artificial lake near to the town of Cirendeu (pronounced [tʃirəndɤ]) in the city of South Tangerang, Indonesia. It was formed by a dam up to 16 metres (52 ft) high which was built by Dutch colonial authorities in 1933. The dam failed on 27 March 2009, draining the lake, with resulting floods killing at least 100 people.
