The RAF is expected to deliver much-needed supplies and reinforcements to Nepal today after more than 3,000 people were killed in the worst earthquake to hit the country in more than 80 years.
A police official said the death toll had risen to 3,218 people with some 6,538 injured following the quake on Saturday.
No Britons are believed to have been killed or injured, according to the Foreign Office but embassy staff have assisted 200 people.
It comes as thousands of people in Kathmandu left homeless by the quake desperately sought shelter, food and medical supplies.
There were reports of the sick and wounded laying out in the open, unable to find beds in the city's devastated hospitals as the overwhelmed authorities struggle to care for the wounded and homeless.
"We are overwhelmed with rescue and assistance requests from all across the country," Deepak Panda, a member of the country's disaster management said.
The number of people known to have died in the Nepal earthquake has risen to 3,218, police told the Reuters news agency.
A further 6,538 are believed to have been injured in the country's worst earthquake for 80 years.
