HANOI, Oct. 7 (Xinhua) -- A section of the Bac Khe 1 hydropower dam in northern Vietnam's Lang Son province collapsed on Tuesday afternoon, Vietnam News Agency reported.
The incident was triggered by prolonged rainfall and excessive water pressure following heavy downpours brought by Typhoon Matmo, the 11th storm to hit Vietnam this year, according to local authorities.
Emergency forces including police, military, and rescue teams have been deployed to stabilize the situation and prevent further damage.
So far, no casualties have been reported, while property damage is still being assessed, the report said. ■
