Pakistan's National Disaster Management Authority announced on Sunday that 109 people have died and some 700,000 others have been affected due to heavy flooding.
It added that military engineers had been deployed to the affected areas in the mountainous north to repair roads and bridges and help rescuers reach people who remain stranded for weeks now.
Pakistani officials have warned of more deaths and destructive consequences should heavy downpour continue, Press TV reported.
Around 350,000 people have been evacuated from the banks of the Indus River in the past two days.
Summer rain monsoon starts in Pakistan from around mid-July and lasts until about the end of August.
Last year’s monsoon left nearly 400 people dead and destroyed thousands of acres of farmland.
