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

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.

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.
