Nepal and China said that around 1,400 people remain missing and at least 180 were confirmed dead from tsunami-like floods likely sparked by the partial collapse of a Himalayan glacier into a valley below.

Floodwaters tore through towns and villages and engulfed Gyirong Port, the major land crossing between China and Nepal, in a wall of water and mud. The avalanche triggering the floods was so powerful that the U.S. Geological Survey initially recorded it as an earthquake, before later recategorizing it.

In Nepal, more than 830 people, including about 500 foreign tourists, remained missing as of Thursday morning, according to the country's National Disaster Risk Reduction and Management Authority. At least 177 bodies have been recovered, the Nepal police have said.

"In this time of crisis that the country is undergoing in an unimaginable manner, the government is engaged in rescue and relief work as quickly as possible," Prime Minister Balendra Shah, who was elected in March after tumultuous protests brought down the government in 2025, wrote in a Facebook post Thursday.

At least 63 Americans and nearly 180 Indians were among the missing, many of whom were pilgrims on their way to lakes in the Nepal and Tibet regions that many Hindus and Buddhists consider sacred.

China said that 558 people, including 260 foreign tourists, were still missing in its Tibet region, which shares a border with Nepal, according to the People's Daily, the Communist Party's newspaper. Three people are confirmed dead, it said.

Many of the bodies in Nepal have been recovered far from the flood-affected northern areas of the country, with the powerful waters having carried many people more than 150 miles to the country's southern plains near India, the country's disaster agency said. Search and rescue operations continue, it said.
