Flooding, landslides kill scores in Nepal's capital

Floods and landslides triggered by heavy downpours in Nepal have killed at least 59 people across the Himalayan country, with rescue teams searching for 44 missing, police said.

"So far, there are 59 dead, 36 wounded and 44 missing," Nepal police spokesman Dan Bahad ur Karki said on Saturday

Karki said more than 200 incidents of flood and landslides have been reported and that the toll was likely to increase further.

Rivers around the capital Kathmandu burst their banks, inundating nearby houses.

"It's scary. I had never seen such kind of devastation in my lifetime before," said Mahamad Shabuddin, 34, who runs a motorbike workshop in the city near the swollen Bagmati River.

Survivors were seen standing on top of buildings or wading through murky waters to get to safety.

"When I went outside in the middle of the night, the water had reached up to my shoulders," Hari Mallah, a 49-year-old truck driver, said.

"My truck is completely under water."

Rescue teams race against time

Large swathes of Nepal have been inundated since Friday, prompting disaster authorities to warn of flash floods in multiple rivers.

Basanta Adhikari, a spokesman for Nepal's National Disaster Risk Reduction and Management Authority, said authorities were working to rescue and get relief to those impacted by the floods.

More than 3,000 security personnel were deployed to assist rescue efforts with helicopters and motorboats.

Rescue teams were using rafts to pull survivors to safety.

Landslides have blocked several highways, leaving hundreds of travellers stranded.

"We have around eight locations, all of them have been blocked due to landslides in different sections of the road," said Kathmandu traffic police officer Bishwaraj Khadka.

All domestic flights out of Kathmandu were cancelled from Friday evening, affecting more than 150 departures.

The summer monsoon brings South Asia 70-80 percent of its annual rainfall.

Monsoon rains from June to September bring widespread death and destruction every year across South Asia, but the numbers of fatal floods and landslides have increased in recent years.

Experts say the climate crisis is increasing their frequency and severity.
