The spokesman for Disaster Management Agency, Priyadi Kardono, said earlier that the floods occurred on Sunday, but then he revised it to before dawn Monday.

Heavy rains were blamed for the disaster at Teluk Wondama district of the province, he said.

“The floods also injured 61 people and destroyed 31 houses. The death toll recorded has increased to 26 now with 61 persons wounded. Seven others still go missing," Kardono told Xinhua by phone.

Earlier, he said the rescue for the missing people by local communities was hampered by fallen trees.

The Head of operation of the Search and Rescue Office for West Papua Muhammad Arifin said dozens of rescuers from Manokwari, the capital of West Papua province, and other cities may arrive to the scene after midnight.

"The team of rescuers departed this afternoon. The journey to the scene will take several hours and they may arrive there after midnight," he told Xinhua by phone from the province.
