Aid slowly arriving at Papaua New Guinea disaster zone

Aid is slowly starting to arrive in the disaster zone of Papaua New Guinea, following last week's catastropihc landslide - but gaining access is still proving to be diffcult. The slip in Yambali village is believed to have killed more than 2000 people, according to Prime Minister James Marape. Vicitms had little to no warning before disaster struck, meaning that the survivors have been left with nothing. There's an immediate need for food, shelter and basic necessities - and there are also concerns about the outbreak of diseases due to unsanitary conditions. Worldwatch's Charlie Dreaver spoke to World Vision's National Director for PNG, Chris Jensen about the ongoing aid efforts on the ground.
