At least seven people were killed and 11 others injured in a hydropower plant accident in Siberia, Russia, today.
The accident occurred at Sayano-Shushenksaya plant, Russia's largest hydroelectric station, which is located on the Yenisei River in East Siberia, the Itar-Tass news agency reported.
The third and fourth culverts at the power station were damaged at around 04:49 Moscow time (00.49 GMT) Monday, destroying walls and submerging the engine room, according to the regional Emergency Situations Ministry.
One of the possible causes of the accident is believed to be a hydraulic surge, Dmitry Kudryavtsev from the Ministry told Russian news sources.
Electricity supplies have been suspended to several major aluminium plants after the production was halted.
Repair work at the plant has already begun.
