An estimated eight million people have been affected by the devastating 7.8-magnitude earthquake that hit Nepal, leaving more than 4,000 dead and 30,000 homeless, the UN said Tuesday. Though international relief has started to arrive, 1.4 million people are still in need of food aid, according to the the most recent report from the UN Office of the Resident Co-Ordinator. The death toll has hit 4,310 and officials say nearly 8,000 are injured. Thousands of people are stranded or homeless in Nepal’s capital Kathmandu, but the situation remains dire in rural areas that have been cut off by landslides and poor weather, said Surya Mohan Adhikari, an official in the district of Gorkha. Meanwhile, all surviving climbers trapped on Mount Everest have been rescued, ITV news reports.
