A disaster agency official says a landslide triggered by torrential rain near a rumbling volcano in western Indonesia has killed at least nine people, AP reported. Sutopo Purwo Nugroho from Indonesia's disaster mitigation agency says several houses were buried when mud gushed down surrounding hills late Saturday in Gundaling village. It's about 12 kilometers (7.4 miles) east of Mount Sinabung in North Sumatra province. He said the bodies of a mother and her 2-year-old son were retrieved from a mound of mud late Saturday. Six victims were found early Sunday, followed by the body of a 10-year-old boy drifting in a river. Seasonal downpours cause dozens of landslides and flash floods each year in Indonesia, a chain of 17,000 islands where millions of people live in mountainous areas or fertile flood plains.
