Difficult conditions frustrate rescue efforts after

UN says authorities working to clear debris after Friday’s disaster, while local media report one couple rescued from the rubble

Unstable terrain, remote locations and damaged roads are hampering relief efforts in Papua New Guinea, where more than 670 people were feared killed in a landslide last week, the United Nations said on Monday.

Emergency crews, led by Papua New Guinea’s defence personnel, were on the ground in the country’s north, but heavy equipment required for the rescue had yet to reach the remote village, as the main road remained cut off and the only access was via helicopter.
