Sudden floods triggered by heavy rains have killed more than 400 people across parts of Pakistan, India-administered Kashmir and Nepal, authorities have said, with scores of people still missing.

Aug 16 (Reuters) - The death toll from heavy rains and flooding in Pakistan has crossed 300, local officials said on Saturday. Hundreds have been killed in recent weeks as Pakistan experienced more rain than usual during the current monsoon season, washing away roads and buildings.

In Pakistan, a helicopter carrying relief supplies to the flood-hit northwestern Bajaur region crashed due to bad weather, killing all five people on board, including two pilots, a government statement said.
