Nepal and China halt rescue efforts as border barrier lake overflows

What the report says

Nepal and China temporarily halted rescue and search operations along their border after a “barrier lake” formed by this week’s flash flood began to overflow, raising fears of a second wave of flooding. According to Al Jazeera’s report, Chinese crews and vehicles pulled back to safer ground as the risk of a breach increased, while Nepalese authorities paused their search effort for about 90 minutes. The danger is centered in the Rasuwa district in Nepal and adjacent areas of Tibet, where residents were seen moving to higher ground.

The disaster began on Wednesday when a glacier collapse sent water, rock, ice and mud rushing through Himalayan valleys, destroying roads, bridges and hydropower facilities and trapping debris that later dammed the river. China has sent engineering teams to survey the site, and officials said the lake’s volume had grown to more than 2.5 million cubic metres by Friday. Local officials in Nepal said water levels were rising downstream, although the size of the surge was not yet clear.

The broader toll is severe. Al Jazeera reported that the death toll across the disaster has climbed above 470, with hundreds still missing in Nepal and Tibet. Thousands of security personnel and rescue workers have been deployed, and helicopters have been used to evacuate survivors and deliver supplies. Relief efforts remain difficult because damaged roads have cut off access to remote valleys, and aid groups warned that an overflow could block deliveries and worsen conditions for already isolated communities.
