The Pakistani authorities announced the crash of a helicopter and the killing of 6 soldiers - including a senior commander - who were on board, as it was on its way to a flood-hit area in the southwest of the country.

The military said in a statement that the helicopter crashed into a mountain during a flood relief operation, killing all on board.

The military helicopter was helping with flood relief operations in Balochistan province when it lost contact with air traffic control on Monday.

Initial investigations indicated that bad weather caused the accident, according to the army statement, ending speculation that insurgents may have targeted the helicopter in one of the most volatile regions of Pakistan.

The military is the most powerful institution in Pakistan, and the civilian authorities rely heavily on it when natural disasters such as floods or earthquakes occur.

It is noteworthy that monsoon floods have killed at least 478 people since mid-June, including at least 136 people in Balochistan alone.
