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

Officials in Pakistan say flash floods triggered by heavy rains have killed at least 49 people in the northwest and elsewhere in the country over the past 24 hours.

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.
