Death toll in Nepal crosses 6100
The official death toll in the massive earthquake in Nepal has crossed 6100, Nepal police say.
A police statement on Friday said 6155 people were killed and 13,402 people were injured in the earthquake as of midnight.
Rescuers have pulled a teenage boy and a woman in her thirties alive from the rubble of Nepal's earthquake, in rare moments of joy five days after a disaster.
The rescue of 15-year-old Pemba Tamang was hailed as a miracle and greeted with cheers from crowds of bystanders who watched the drama unfold at a ruined guesthouse in Kathmandu on Thursday.
Just hours later, a team pulled a kitchen worker in her thirties named Krishna Devi Khadka from the rubble of another hotel just streets away to loud cheers from the multinational team of rescuers who had worked into the night to save her.
Pemba was fitted with a neck brace and raced to a field hospital where he was found to have only minor cuts and bruises.
"I never thought I would make it out alive," the teenager told AFP at the Israeli military-run facility.
Pemba, who worked at the guesthouse as a bellboy, said he had been eating lunch next to reception when the ground started shaking.
"I tried to run but ... something fell on my head and I lost consciousness - I've no idea for how long," he said.
The recovery of another teenager's body from the same area underlined how the prospects of finding further survivors of Saturday's 7.8-magnitude quake were becoming more remote.
Libby Weiss, a spokeswoman at the Israeli field hospital, said Pemba was doing "remarkably well", saying it was the longest she'd heard of someone trapped under rubble surviving.
"I don't have any logical explanation. It is miraculous. It is a wonderful thing to see in all this destruction."
Emergency workers from France, Norway and Israel operating with the Nepal army and using listening devices to find survivors took 10 hours to free Khadka once they had discovered her.
"She was injured but she was conscious and talking," a Nepal army major said.
Launching an appeal for $US415 million ($A518 million) in aid, the UN has said it will take a marathon effort to help the people of one of Asia's poorest countries.
Meanwhile, the International Monetary Fund said it was ready to extend aid to Nepal and would send a team to assess the situation "as soon as possible".
Although the number of aftershocks since Saturday's quake has subsided, fresh tremors were felt in Kathmandu overnight.
They have no idea of the chaos they have been born into.
Four babies have been delivered each day in a 50-bed hospital run by Swiss doctors since a 7.8 magnitude earthquake shattered the Nepalese town of Gorkha.
Outside, bad weather prevents helicopters delivering food, water and temporary shelter.
Locals sit in the rain and cold, too scared to go inside for fear of aftershocks.
They see aid organisations on the ground, but there is little to hand out with most planes hovering in a perpetual circle above the airport, waiting their turn to land.
World Vision CEO Tim Costello says that's because foreigners are being prioritised over getting aid to the locals.
"There's a bottleneck at the airport with foreign nationals getting out and foreign governments' first priority is them," he told AAP from Gorkha.
"Certainly helicopters have been diverted to foreigners at Everest and around that area."
Gorkha is at the epicentre of Saturday's earthquake, which killed more than 5000 people.
Mr Costello is there distributing tarpaulins to some of the 270,000 locals.
"Everything has been handed out," he said.
"There's not enough helicopters."
Tents line the outskirts of the hospital and Mr Costello says patients lie in pain awaiting operations.
There's been reports of amputations without anaesthetic, but World Vision hasn't been able to confirm them and there's an anaesthetist at the hospital.
It's the people in nearby villages, most impossible to reach by road, that concern Mr Costello.
"We don't know what's happening in those villages," he said.
People are surviving by sharing what food they have, mainly grains stored under their houses.
They're scared in Gorkha but Mr Costello says they're not furious.
"They have very low expectations of their government," he said.
"If this was Australian villages there would be outrage."
World Vision employees also lost their homes in the tremor.
"Many of our staff are actually sleeping outside because their houses were destroyed and then they're getting up and going to work to help others," Mr Costello said.
Mr Costello urges Australians to continue donating for Nepal, saying the rebuild will be costly.
