Torrential rains have triggered flash floods and a landslide on Indonesia's Sumatra island, killing at least 19 people and leaving 7 others missing, officials said Sunday morning local time.

Tons of mud, rocks and uprooted trees rolled down a mountain late Friday, reaching a river that burst its banks and tore through mountainside villages in Pesisir Selatan district of West Sumatra province, said Doni Yusrizal, who heads the local disaster management agency.

Rescuers pulled out seven bodies in the worst-hit village of Koto XI Tarusan, and recovered two others in two neighboring villages, said National Disaster Management Agency's spokesperson Yusrizal. Ten are still missing.

He said that 46,000 people had fled to a temporary government shelter after the flood and landslide buried 14 houses while 20,000 houses were flooded up to the roof.CBS News
