Large parts of Pakistan's north-west remain swamped after flooding caused by the worst monsoon rains in the country's history.

The disaster has affected some 1m people. Some tried to return to their homes on Sunday.

This man had tied a rooster - a precious possession - to his head before evacuating his home in the town of Nowshera and swimming to higher ground.

These flood victims in Nowshera found shelter in a mosque.

About 30,000 troops have been mobilised to help those stranded or displaced, with helicopters distributing aid supplies.
