PADANG SIDEMPUAN, Indonesia: Indonesia’s president told survivors of last week’s devastating floods that help was arriving to those in need Monday as Asian governments scaled up their responses to a disaster that has left more than 1,000 dead in three countries.

Hundreds more are missing following flooding and landslides in the past week, which killed at least 469 people in Indonesia, 334 in Sri Lanka and 170 in Thailand, authorities said.

Indonesia President Prabowo Subianto pledged to rebuild infrastructure while visiting areas impacted by floods and landslides on Sumatra island that left thousands homeless and 474 people missing as of Monday.

Some areas of Indonesia remained unreachable Monday after the disaster damaged roads and downed communications lines, with residents in impacted areas relying on aircraft delivering supplies. Flooding displaced 290,700 people in North Sumatra, West Sumatra and Aceh provinces, the National Disaster Management Agency said.

Prabowo, who visited North Sumatra on Monday and was expected to West Sumatra and Aceh during the day, said the government’s response is reaching those in need.
