Pakistan has received higher-than-normal monsoon rainfall this year, triggering floods and mudslides that have killed more than 540 people since June 26.

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.

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.
