Pakistan has restored 70% of electricity and reopened damaged roads in the north and northwest after flash floods killed more than 300 people.

Rescuers were racing against time to find survivors after flash floods killed at least 337 people in Pakistan 's Khyber Pakhtunkhwa province. The northwestern province was struck by cloudbursts and torrential monsoon downpours on Friday, triggering flash floods and landslides in the mountainous Buner district.

Pakistani authorities are defending their response to flash floods that killed more than 200 people in a single northwestern district this week.
