Villagers desperate to find earthquake survivors dug with bare hands into collapsed homes and schools in the Pakistani town of Balakot where children had been heard crying under the rubble.
As Pakistani military helicopters ferried troops and supplies to some areas, there was no sign of government help in Balakot, a northern town of 30,000 where the quake levelled the main bazaar, crushing shoppers and sending gas cylinders, bricks, tomatoes and onions spilling into the streets.
Injured people covered by shawls lay in the street, waiting for medical care. Residents carried bodies on wooden planks.
The bodies of four children, age four to six, lay under a sheet of corrugated iron. Relatives said they were trying to find sheets to wrap the bodies.
"We don't have anything to bury them with," said a cousin, Saqib Swati.
Nearby, business administration student Faizan Farooq, aged 19, stood outside the rubble of his four-storey school, where at least 250 pupils were feared trapped.
Dozens of villagers, some with sledgehammers but many without any tools, pulled at debris and carried away bodies.
Mr Farooq said at first, he'd heard children crying for help under the rubble.
"Now there's no sign of life," he said. "We can't do this without the army's help. Nobody has come to help us."
A 40-year-old man at the scene wept, saying four of his children were under the debris.
Elsewhere in Balakot, shop owner Mohammed Iqbal said two primary schools also collapsed and more than 500 students were feared dead.

Several International Federation of Red Cross trucks laden with tents, food, medicine and other aid were trying to reach the hard-hit areas in Pakistan, said Layla Berlemont, a spokeswoman for the group in Islamabad. She said the agency would use aircraft if the roads are blocked.
The US Geological Survey reported 22 aftershocks - one of magnitude 6.2 - in the 24 hours after the main quake, which the USGS initially reported as 7.6 but later revised to 7.7. Most deaths in India's Jammu-Kashmir state were in the border towns of Uri, Tangdar and Punch and in the city of Srinagar, said BB Vyas, the state's divisional commissioner.
