Papua New Guinea landslide: rescuers say they do not expect to find survivors under rubble

Officials are still trying to pinpoint the exact death toll, as rescue teams are set to begin using heavy machinery to recover the dead

Officials in Papua New Guinea have said they do not expect to find survivors under the rubble of a massive landslide in the country's remote north, with the exact number of dead under almost two storeys of debris and mud still unknown.

Heavy equipment and aid have been slow to arrive to the site of the landslide - which hit almost a week ago - because of the treacherous mountain terrain, a damaged bridge on the main road, and tribal unrest in the area.
