Around 1.4 million are in need of food aid, according to a statement by the UN's Office for the Coordination of Humanitarian Affairs, with many more needing water and shelter. The UN said it based its figures on the assumption that half the people in stricken areas would need help, as first-hand access was still limited. The government raised the death toll to 4,698, including 1,469 in Kathmandu, Kantipur TV reported, as volunteers searched for dead and missing from Saturday's quake, which also left nearly 8,000 injured.
Across the border in China's Tibet Autonomous Region, authorities said 25 people were killed by the quake, and 117 injured, when nearly 80% of houses collapsed in the three counties of Gyirong, Nyalam and Tingri. Around 20 aftershocks had been felt in Tibet since Saturday's quake, the report said. Tremors were also felt across Nepal and in neighbouring India Tuesday, Indian broadcaster NDTV said.
Aid was pouring in from around the world, despite limited capacity at Kathmandu airport, which saw many flights delayed and diverted.
Taiwan's government is not recognised by China, which shares a Himalayan border with Nepal and contributed troops and material to its neighbour's quake relief effort.
