At least 194 people have died in the last 24 hours in heavy monsoon floods and landslides in Pakistan and Pakistan-administered Kashmir.

Most of the deaths, 180, were recorded by disaster authorities in the mountainous Khyber Pakhtunkhwa province in north-west Pakistan. At least 30 homes were destroyed and a rescue helicopter crashed during operations, killing its five crew.

Nine more people were killed in Pakistan-administered Kashmir, while five died in the northern Gilgit-Baltistan region, it said.

Government forecasters said heavy rainfall was expected until 21 August in the northwest of the country, where several areas have been declared disaster zones.

In Buner, one survivor told AFP the floods arrived like "doomsday".

"I heard a loud noise as if the mountain was sliding. I rushed outside and saw the entire area shaking, like it was the end of the world," said Azizullah.

"The ground was trembling due to the force of the water, and it felt like death was staring me in the face."

The chief minister of Khyber Pakhtunkhwa, Ali Amin Gadapur, said that the M-17 helicopter crashed due to bad weather while flying to Bajaur, a region bordering Afghanistan.

In Bajaur, a crowd amassed around an excavator trawling a mud-soaked hill, AFP photos showed. Funeral prayers began in a paddock nearby, with people grieving in front of several bodies covered by blankets.

In the Indian-administered part of Kashmir, rescuers pulled bodies from mud and rubble on Friday after a flood crashed through a Himalayan village, killing at least 60 people and washing away dozens more.

Monsoon rains between June and September deliver about three-quarters of South Asia's annual rainfall. Landslides and flooding are common and than 300 people have died in this year's season.

In July, Punjab, home to nearly half of Pakistan's 255 million people, recorded 73% more rainfall than the previous year and more deaths than in the entire previous monsoon.

Scientists say that climate change has made weather events more extreme and more frequent.
