Bombing in Kabardino-Balkaria hydroelectric power station kills 2

A hydroelectric power station in Russia's Kabardino-Balkaria region hase come under a bomb and gun attack.

Two guards have been killed and two others injured, BBC News reported.

Four bombs caused a fire in the Baksan plant's engine room which was later extinguished, prosecutors said. Supplies to the electricity grid were not affected, according to the state-run RusHydro Company.

The plant on the Baksan River lies in a part of the North Caucasus gripped by a violent Islamist insurgency.

RusHydro said in a statement on its website that explosions had hit the plant at 0525 local time (0125 GMT) on Wednesday.

The attackers detonated four explosive devices in the 25-megawatt Baksan plant while a fifth failed to go off, prosecutors said.

According to police spokesman Adlan Kakakuyev, two cars carrying half a dozen assailants had attacked the plant, shooting two guards and wounding three other people.

No one has claimed responsibility for the bombing and the attack.

The Baksan hydroelectric power station was built in the 1930s.
