An additional 83 people are injured, said Priyadi Kardono of Indonesia's National Disaster Mitigation Agency in Jakarta. He said 27 were missing, but Angung Laksono, the coordinating minister for people's welfare, told a radio station that 68 people were missing and 3,000 had been displaced.

The hardest-hit area is the remote location of Teluk Wondama, some eight to 10 hours by ship from Manokari, West Papau, officials said. Communication lines there were also disrupted.

The country's Ministry of Health and government agencies have sent tents, blankets, clothes and food to the region.

It is monsoon season in Indonesia, and flooding is not unusual. However, the Bureau of Meteorology, Climatology and Geophysics is forecasting unusually heavy rains this year.
