Villages in the mountainous north of Pakistan have received their first shipments of supplies four days after the devastating tremor. Local officials say the death toll may be as high 40,000 across the region.The rescue effort has focused on searching for survivors in the rubble. But with temperatures falling and the threat of illness growing, it has become crucial to get essential supplies to affected areas. Both sides of the frontline of divided Kashmir have been hit hard. Where once there were villages, entire communities are now without shelter. India and Pakistan have put aside mutual hostilities in the relief effort, and India has started to send aid to its neighbour. Pledges of financial assistance have been pouring in from around the world. But with some two million people thought to be left homeless the UN has said more is needed.
