The death toll from a flash flood disaster in the Nepal-Tibet border region has climbed to at least 750 people as of Sunday, according to officials from Nepal and China. More than 3,000 individuals remain missing in the wake of the disaster.
In Nepal, authorities reported that 734 bodies had been recovered by Sunday, with 2,498 people still unaccounted for. On the Chinese side of the border, state-run Xinhua News Agency confirmed at least 16 fatalities and reported 546 people missing.
Among those missing, at least 90 Americans were unaccounted for as of Friday, a State Department spokesperson confirmed. The department also announced that five Americans had been successfully evacuated. The U.S. embassies in Nepal and China are engaged in efforts to assist American citizens and support relief operations.
"There is no higher priority for us than the safety of American citizens," the State Department said in a statement released Saturday. The U.S. will provide $3.6 million in humanitarian aid, including emergency food assistance for up to 10,000 flood-affected households.
The flooding occurred Wednesday around 8:40 a.m. local time in the northern Rasuwa district, which borders Tibet. The deluge inundated areas along the Trishuli River, destroying buildings and damaging critical infrastructure such as bridges and roadways.
An analysis of verified video and satellite imagery indicates that the destructive wall of water, originating from the mountains along the Nepal-Tibet border, caused damage extending at least 62 miles downstream into Nepal. The flood was reportedly triggered by a landslide approximately 12 miles northeast of the Rasuwagadhi border crossing. A 5.2-magnitude landslide was registered in Nepal on Wednesday, according to the U.S. Geological Survey. The landslide originated on a cliff face at an elevation of about 16,000 feet, with the debris avalanche descending 6,000 feet down the slope.
