Anguished Pakistanis are searching remote areas for bodies swept away by weekend flash floods as the death toll has reached 277.

Most of the deaths were recorded by disaster authorities in the mountainous Khyber Pakhtunkhwa province in north-west Pakistan. At least 74 homes have been damaged, while a rescue helicopter crashed during operations, killing its five crew.

A flash flood in northwest Pakistan has killed 337 people. The local government has been accused of failing to provide early warnings.
