A changing climate has made residents of river-carved mountainous areas more vulnerable to sudden, heavy rains.

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.
