Anguished Pakistanis are searching remote areas for bodies swept away by weekend flash floods as the death toll has reached 277.

The Prime Minister assured the flood affectees of the Federal Government and Pakistan Army's unwavering commitment to extend maximum support in this critical hour.

Pakistan has restored 70 percent of electricity service and reopened damaged roads in the north and northwest after flash floods killed more than 300 people, officials say. Information Minister Attaullah Tarar said on Tuesday that engineers were working to fully restore the electricity system that was knocked out by flooding last week.

Officials say rescuers have recovered dozens more bodies from the rubble of collapsed homes in a northwestern district of Pakistan, bringing the death toll to at least 274, as authorities defended their response to the flooding and said they did not need any foreign help at this point.

The death toll in the flood-ravaged province of Pakistan's Khyber Pakhtunkhwa (KP) has surged to 365, as torrential rains and flash floods continue to batter the region, with new casualties and destruction reported across several districts.

More than 20 people have died in a fresh spell of monsoon rain in Pakistan, the country’s disaster management agency said on Wednesday. Torrential downpours across Pakistan over the past week have caused flooding and landslides that swept away entire villages,

Heavier than usual rains and sudden cloudbursts during this monsoon season kill more than 300 people in recent days.
