Eight months after a 7.8-magnitude quake killed almost 8,900 people and destroyed some half a million homes, thousands of survivors are bracing for the Himalayan winter without proper clothes, bedding or shelter.
In the remote village of Philim, close to the quake's epicentre in western Nepal, the disaster reduced the school's dormitory to rubble, forcing some 200 children to take refuge in tents.
The flimsy structures offer little protection against bone-chilling winds that whip through the village where overnight temperatures currently hover around two degrees Celsius and are set to fall further.
Many of the children live hours from Philim but are staying in the tents because they can no longer commute from their homes after quake-triggered landslides blocked hillside trails.

"We have limited food stocks -- no vegetables, enough lentils to last a week, cooking oil for 10 days perhaps. But most of all, I worry about the cold and its impact on my kids," school headmaster Mukti Adhikari said.
"It's too difficult for them to go home, so we keep them here... But now I am worried they will freeze to death since no one has adequate clothing or proper bedding," he told AFP.
But its failure to establish the National Reconstruction Authority (NRA) has delayed the start of rebuilding, meaning thousands are still homeless.
Aid workers are now scrambling to deliver emergency supplies before snowfall shuts access altogether to villages like Philim.
"We are closing in on a deadline -- we are aware that a day will come soon when we won't be able to go up those trails," said World Food Programme country director Pippa Bradford.
But severe fuel shortages have hamstrung their race against time, with hundreds of trucks carrying petrol and other vital supplies stuck at the border between Nepal and India, the country's main supplier.
Movement of cargo through other checkpoints has also slowed to a crawl, prompting Nepal to accuse India, which has criticised the charter, of enforcing an "unofficial blockade" -- a charge New Delhi denies.
