On the the road to the Allai Valley, men try to push a truck that is stuck in mud and landslide debris and which is blocking other trucks full of humanitarian aid and earthquake survivors returning to their mountain villages, Battagram District, Pakistan's Northwest Frontier Province. The region was one of the worst-hit by the October 2005 earthquake, and aftershocks and heavy rains continue to trigger landslides, which have hampered reconstruction efforts and the return of earthquake survivors to their mountain villages from the low altitude tent camps where many spent the winter.
