Flashfloods and landslides struck West Java province in western parts of Indonesia overnight and into Wednesday morning, leaving 10 people dead, 30 injured, three missing and hundreds of others displaced, China's Xinhua news agency reported a disaster agency spokesman as saying.

The flashfloods occurred at about 1am Jakarta time in several areas at Garut district as water in two rivers overflowed due to heavy downpours, Sutopo Purwo Nugroho, spokesman of the national disaster agency told Xinhua by phone.

Eight people have been killed, 30 wounded and one has gone missing in the flashfloods, he said.

In Sumedang district, landslides hit two houses, leaving two people dead and two others missing at about 10pm Jakarta time Tuesday, Sutopo added.

Search operations for the missing as well as emergency relief efforts are underway, involving soldiers, police, those from local disaster agency and search and rescue office.

Hundreds of affected people have been moved into government office buildings and military stations, Sutopo added.

Indonesia is frequently hit by floods and landslides during heavy rains. -- BERNAMA
