Anger is mounting among survivors of the South Asia earthquake over the apparently slow response to a disaster that killed at least 20,000.
As law and order breaks down, looting has been reported in Pakistan. Across the border in India meanwhile, rescuers have yet to reach some remote villages.
But the first significant deliveries of aid have arrived in the wrecked capital of Pakistani-run Kashmir, Muzaffarabad.
And in Balakot, several children and a woman were pulled alive from rubble.
A specialist French rescue team retrieved five children from the wreckage of a school in the town, one of the areas worst hit in Saturday's giant quake.
At least a hundred children are thought to have been inside when the earthquake struck, bringing the huge concrete roof straight down on top of them.
Using sniffer dogs and special cameras, the French team found four boys and one girl alive with only minor injuries in the early hours of Tuesday.
In the Pakistani capital, Islamabad, British rescuers brought an Iraqi woman and her two-year-old son out of the rubble of a collapsed apartment building unscathed.
The same team also made contact with two women under the rubble and hoped to extract them in turn.

In the remote town of Bagh, magistrate Raja Mohamed Irshad said people were not mourning their dead, but their "ties with the government".
Pakistani Interior Minister Aftab Ahmad Khan Sherpao said the government had done its best to deliver aid, but the quake had blocked roads and cut communications.
