China Warns Nepal Barrier Lake Could Breach Within 72 Hours
A glacier collapse and mudslide caused huge floods near Nepal and Tibet.
The rushing water carried mud and rocks into rivers and damaged homes, roads and power projects.
The debris also blocked a river and created a new lake.
This lake already contains about 2 million cubic metres of water and is overflowing.
Officials think another 3 million cubic metres could enter it within three days.
If the barrier breaks, a large wave of water could rush downstream.
Many people have died or are missing, but agencies have reported different numbers.
China and Nepal are watching the lake and sending rescue workers.
Villages in dangerous areas on the Tibetan side have been evacuated.
China warned that a barrier lake near the Nepal-Tibet border could breach within three days and cause further flooding.
The lake contained about 2 million cubic metres of water Thursday and could receive another 3 million cubic metres.
The lake is already overflowing and formed after debris from a glacier-related flood blocked a river.
Casualty figures differ: Nepal reported 270 deaths and 826 missing, while other reports cited 359 recovered bodies and more than 1,300 missing overall.
China evacuated Tibetan villages, monitored the lake, ran flood simulations and deployed rescue teams, engineers and relief agencies.
