At least 389 people have been confirmed dead following catastrophic flash floods that swept through the Nepal-Tibet border region, as search and rescue operations continued on Thursday. Authorities reported over 1,300 people missing in total, with the number of those unaccounted for fluctuating as recovery efforts intensified.

The devastating floods occurred on Wednesday morning in the northern Rasuwa district, along the border with Tibet. The disaster inundated areas along the Trishuli River, burying structures and damaging critical infrastructure like bridges and roads.

According to the Nepal Tourism Board, 66 American citizens are among the missing. The U.S. State Department confirmed it was aware of approximately 90 Americans impacted by the floods and stated that three American citizens had been safely rescued. The department has not been informed of any American fatalities.

Across the border in China's Tibet region, state-run media reported three confirmed deaths and 558 individuals still missing. The Nepal National Disaster Risk Reduction and Management Authority indicated that as of Thursday morning, 826 people were out of contact, including 579 tourists, of whom 476 were foreign nationals and 114 were Nepali citizens.

Nepal's Prime Minister's office expressed profound sorrow over the loss of life and extended condolences to the bereaved families. Search and rescue efforts, involving the Nepali Army, were reported to be continuing through the night.

The Nepal Tourism Board also reported that two Americans were among a group of 27 foreign tourists rescued from the Timure and Bhotekoshi area of Rasuwa, a region heavily affected by the disaster.

Dramatic video footage captured the extent of the flooding, which initial reports suggest was triggered by a massive landslide and the tumbling of a glacier. The disaster has left a trail of destruction, with images showing vast areas covered in mud and debris.

This natural disaster has highlighted the vulnerability of the border region to extreme weather events. Authorities are continuing efforts to locate the missing and assess the full scale of the devastation, while international agencies monitor the situation and offer support.
