Sudden floods triggered by heavy rains have killed more than 200 people across parts of Pakistan, India-administered Kashmir and Nepal, authorities have said, as scores of people remain missing.

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.

Anguished Pakistanis searched remote areas for bodies swept away by weekend flash floods as the death toll reached 277 on Monday, while one official replied to the lack of evacuation warnings by saying people should have built homes elsewhere.
