Papua New Guinea landslide death toll exceeds 670, says UN agency

Emergency workers give up hope of finding survivors of Friday's landslide as tribal warfare threatens rescue effort

More than 670 people are believed to have been killed in a massive landslide in Papua New Guinea, the UN migration agency has said, as emergency workers and relatives gave up hope that any survivors would be found.

The death toll from the landslide on Friday had been estimated at more than 300, but 48 hours later the International Organization for Migration (IOM) said it may be more than double that, with the full extent of destruction still unclear.
