More than 10,000 people are now known to have been injured in Saturday's 7.8-magnitude quake, the division's chief Rameshwor Dangal told AFP.

Hungry and desperate villagers rushed towards relief helicopters in remote areas of Nepal Tuesday, begging to be airlifted to safety, four days after a monster earthquake killed more than 5,000 people.

"The ground keeps shaking, even this morning it did. Every time it feels like we will be swallowed, that we will die now. I want to get out of here!" said Sita Gurung, 24, whose home had been ruined.

As the Himalayan nation's Prime Minister Sushil Koirala said getting help to remote areas was a "major challenge", aid finally began reaching areas that had to fend for themselves since Saturday's 7.8-magnitude quake.

The official toll in Nepal alone stood at 5,057 while more than 100 people died in neighbouring countries such as India and China.
