The U.N. agency has officials at the scene in Enga province helping shelter 1,600 displaced people. The agency estimates 670 villagers died, while Papua New Guinea’s government has told the United Nations it thinks more than 2,000 people were buried. Five bodies had been retrieved from the rubble by Monday.

“We are hearing suggestions that another landslide can happen and maybe 8,000 people need to be evacuated,” Aktoprak told The Associated Press.
