BUNER, Pakistan (AP) — Rescuers in northwest Pakistan pulled 63 more bodies overnight from homes flattened by landslides and flash floods, raising the death toll from rain-related incidents to at least 220, officials said Saturday.

The country has endured heavier rain during monsoon seasons, which scientists have attributed to climate change. The authorities said that at least 194 people died on Friday.

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.

A Pakistani official says the death toll from flash floods in the country's northwest has risen to 274 after rescuers recovered dozens of bodies from the rubble of collapsed houses.

More than 150 people are missing in northwest Pakistan, the head of the provincial disaster authority said Sunday, after flash floods that have killed at least 344 people in the country.
