Flooding in a northwest Pakistani district has killed at least 220 people, officials said Saturday, as rescuers pulled 63 more bodies overnight from homes flattened by flash floods and landslides.

Pakistan has received higher-than-normal monsoon rainfall this year, which experts link to climate change, triggering floods and mudslides that have killed some 541 people since June 26, according to the National Disaster Management Authority.

Hundreds of rescue workers are still searching for survivors in Buner, one of several places in Khyber Pakhtunkhwa province where torrential rains and cloudbursts caused massive flooding on Friday, said Mohammad Suhail, a spokesman for the emergency services. Dozens of homes were swept away.

First responders have been trying to recover bodies from the worst-hit villages of Pir Baba and Malik Pura, where most of the fatalities were, said Kashif Qayyum, a deputy commissioner in Buner.

A local police officer said floodwaters carrying hundreds of boulders struck and flattened homes within minutes.

Rescuers said they saw large swathes of Pir Baba village destroyed, wrecked homes, and giant rocks filling the streets as the water started to recede.

Mourners attended mass funerals on Saturday, while authorities supplied tents and food items to flood-affected people in Buner.

According to the provincial disaster management authority, at least 351 people have died in rain-related incidents this week across Khyber Pakhtunkhwa and the northern region of Gilgit-Baltistan.

Nearly 300 kilometers (about 186 miles) away in Indian-controlled Kashmir, rescuers scoured the remote village of Chositi in the district of Kishtwar on Saturday, looking for dozens of missing people after it was hit by flash floods two days ago, killing 60 and injuring some 150, about 50 in critical condition.

Thursday's floods struck during an annual Hindu pilgrimage in the area. Authorities have rescued over 300 people, while some 4,000 pilgrims have been evacuated to safety.

Such cloudbursts are increasingly common in India’s Himalayan regions and Pakistan’s northern areas, and experts have said climate change is a contributing factor.

Pakistani officials said rescuers since Thursday have evacuated more than 3,500 tourists trapped in flood-hit areas across the country.

Many travellers have ignored government warnings about avoiding vulnerable regions in the north and northwest.

Pakistan witnessed its worst-ever monsoon season in 2022. It killed more than 1,700 people and caused an estimated $40 billion in damage.
