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.

At least 46 people died and more than 200 were missing following sudden, heavy rain in Indian Kashmir, officials said on Thursday, the second such disaster in the Himalayas in a little over a week.

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.
