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.

At least 60 people were killed, more than 100 injured and another 200 still missing, Chief Minister of Jammu and Kashmir Omar Abdullah told reporters on Friday. The Himalayas are prone to floods and landslides, but some scientists say the intensity and frequency of these events are increasing due to climate change.
