Rescue workers in northwestern Pakistan expanded relief operations Sunday after flash floods killed more than 220 people in a single district, officials said.

Flash floods caused by torrential rains in a remote village in India-controlled Kashmir have left at least 56 people dead and scores missing, according to authorities.

By Saturday, 307 were confirmed dead, with more people missing, according to the Provincial Disaster Management Authority. Parts of neighbouring India and Nepal have also been hit hard by heavy rains,
