Russian officials have warned it is unlikely any of the 64 workers trapped within Russia's largest hydro-electric power plant after a blast will survive.
Twelve people are already confirmed dead after the explosion at the Sayano-Shushenskaya power plant in Siberia.
Emergencies Minister Sergei Shoigu said groups of divers were searching for survivors in the flooded turbine hall.
The blast's cause is unknown but reports said investigators believed a transformer exploded during repairs.

Looking at the videos and pictures I can only imagine that they had a series of failures all at once. Oil filled output transformers can generate explosive gas if not kept in good repair, and large industrial generators are often cooled by hydrogen. I suspect an explosion in one touched off an explosion in the other... that is if it was indeed an accident.
70 people gone in one stroke... yikes!
