Buner, Pakistan — Pakistan issued a flood alert Wednesday for some southern districts, warning of torrential rains, as rescue teams continued searching for missing people in the country's northwest, where severe floods killed hundreds over the past week.

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

A deluge of rain triggered floods and landslides, sweeping people away and flooding and destroying homes, officials said.

Pope Leo XIV offered prayers and expressed his closeness for the victims of severe flooding that hit Pakistan, India and Nepal. The Pope shared his prayers “for the victims and their families, and for all those who are suffering as a result of this calamity,” Vatican News reported on Aug. 18.

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.
