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.

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

According to the National Disaster Agency, the intensity of this year's monsoon is about 50% to 60% higher than last year.

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

Khyber Pakhtunkhwa government's MI-17 helicopter had taken off from Peshawar for Bajaur when contact was lost over Mohmand tribal district, according to initial reports.
