One month after the earthquake that devastated northern Pakistan and has killed at least 73,000, some half a million people remain without shelter.
Aid agencies fear the onset of the bitter Himalayan winter could result in another humanitarian crisis with thousands of deaths.
The UN has said its appeal for aid is currently just 15 percent funded, with only $85 million of $550 million committed. In addition there are $49 million in unconfirmed pledges, which if confirmed, will bring the total response to 24 per cent.
Some 3.5 million people were affected by the earthquake, which measured 7.5 on the Richter scale, across an area of 30,000 sq km.
Most hospitals, schools and government buildings were destroyed. Landslides have blocked roads, rockslides are a constant danger and villages perched high on isolated mountain ranges and deep in remote valleys mean hundreds of thousands of survivors have still not received aid.
An estimated 790,000 children aged between five and 18 years were affected by the earthquake and 10,000 schools damaged or destroyed.
Meanwhile, Pakistan and India reopened the main border crossing in Kashmir today to help survivors of last month's earthquake that devastated the region.
The crossing between the Pakistani town of Chakothi and the Indian town of Uri was one of five points along the Line of Control the South Asian rivals agreed to open to facilitate aid and allow divided families to meet.
However, procedural difficulties have prevented vital relief trucks and people from crossing.
