Help has still not reached half a million people affected by the tragic South Asian earthquake, the United Nations said on Tuesday.
This comes as a row between Pakistan and India over staffing helicopters is delaying rescue operations.
There are also fears that many more people could die from bad winter weather and untreated injuries.
More than 40,000 people have been confirmed dead since the earthquake hit on 8 October.
Hundreds of villages have not received any help at all, according to James Morris from the UN's World Food Programme.
"The aid agencies have managed to give some help to hundreds of thousands of people, but there are an estimated half a million more people out there in desperate need, who no one has managed to reach," he said.
On Monday, Pakistan and India were rowing over whether Indian helicopters and crew could join the rescue operations because Pakistan wanted to crew the aircrafts itself.
If the historic rivals agree a way forward, this could potentially double the number of rescue helicopters operating in Pakistan and Pakistan-administered Kashmir.
