Authorities urge villagers to move to safer places after a river bursts its banks in the central part of the country.

Flash floods have hit central Nepal, sweeping away houses and leaving at least five people missing, according to officials, weeks after devastating flooding in the country that killed hundreds.

A landslide in Chumnubri village in Gorkha district, about 100km (62 miles) west of Kathmandu, blocked the Budhi Gandaki River on Saturday, leading to downstream flooding, authorities said.

Two women and three men were unaccounted for, and there are no reports of casualties, said the National Disaster Risk Reduction and Management Authority (NDRRMA).

According to the agency, at least 82 people, including nine foreigners, have been rescued from the affected areas.

The flood swept away about a dozen houses and two suspension bridges and damaged a hydroelectric project camp, carrying some of the construction equipment away, authorities said.

A muddy torrent washed away a highway bridge connecting Gorkha with the neighbouring Dhading district, said NDRRMA Chief Executive Dharam Raj Uprety.

Evacuation order

The Budhi Gandaki is a tributary of the Trishuli River, downstream from another tributary where a glacier collapse caused a catastrophic flood in August that killed 1,457 people, with thousands still missing.

“We have asked villagers living along the riverbanks downstream to evacuate and remain safe,” said Dharmendra Kumar Mishra, Gorkha district’s most senior bureaucrat.

National disaster authorities alerted people living along the river in the Gorkha, Tanahun, Chitwan, East Nawalparasi and West Nawalparasi districts about the flood.

“Please help ensure that people in at-risk areas are moved to safe locations in time and assist search and rescue operations as needed,” the NDRRMA said in a social media post.

Officials said army and police rescue personnel had reached the area and were also monitoring the situation from a helicopter.

“The flood looked similar… It was very scary, and it still feels like a nightmare for us,” said local official Laxmi Gurung of Chumnubri rural municipality.

“Our house is gone, we have no electricity… but there have been no casualties.”

Heavy rainfall in late September also triggered floods and landslides, killing at least 21 people, according to the disaster agency.
