Nepal earthquake: Thousands fleeing Kathmandu after quake
The prime minister of Nepal says the country is "on a war footing" as it tries to help survivors of the earthquake.
Sushil Koirala said the government was doing all it could but was overwhelmed.
Officials say the death toll from the 7.8-magnitude quake has now passed 5,000, but could reach 10,000.
The UN has estimated that eight million people have been affected - more than a quarter of the population.
The BBC's Yogita Limaye, who is in Kathmandu, says tens of thousands are fleeing the city fearing aftershocks, collapsing buildings and outbreaks of disease.
