Pakistani officials say flash floods overnight have killed 30 people in northern Pakistan, near the Afghan border.

Maghfirat Shah, the mayor of Chitral district, says heavy monsoon rains and flash floods overnight washed away a mosque and several houses in Arsun, an area of Chitral.

He says the bad weather hampered rescue efforts but by Sunday morning most bodies had been recovered and identified.

A spokesman for the disaster management authority, Yousuf Zia, says search crews have recovered the bodies of seven worshippers swept away when the mosque was struck by floods.

He says nearby roads had been washed away and so authorities had called for helicopters to join rescue and relief operations in the remote area.

Chitral is in the far north of Pakistan, bordering Afghanistan's Badakhshan province.
