At least six people died and four others are missing after they were struck by a flash flood on the Indonesian island of Sulawesi. The flood, which swept away about 30 homes in the Polewali district of West Sulawesi province Saturday, was caused by a river that burst its banks following day-long heavy rain. "So far we have recovered six bodies but four people are still reported missing," Rustam Pakaya, head of the Health Ministry's crisis centre said. He said at least seven villages in the province had been hit by flood waters more than 1.5 metres deep following torrential rain this week.
