Following a terrorist attack on a power station in Kabardino-Balkaria, President Dmitry Medvedev has been briefed on the measures being taken in the North Caucasian republic to boost security at strategic facilities. According to the Kremlin press service, the Russian head of state - who is currently on a visit to Finland - was also told that electricity supplies in the region were not disrupted, writes Interfax news agency. Federal Security chief Aleksandr Bortnikov informed Medvedev "about the investigation into the blasts at the Baksan hydropower plant and the measures being taken to normalize the situation and to tighten security at strategic facilities," a Kremlin spokesman told journalists. The spokesperson also said that the president of Kabardino-Balkaria, Arsen Kanokov, told Medvedev about what is being done to deal with the aftermath of the gun and bomb attack on the Baksan power plant on Wednesday morning. Early in the morning on July 21, the suspected militants burst into the station and killed two people and injured two more. "Two security guards - a 41-year-old warrant officer and a senior lieutenant of 25 - were killed; the criminals took their weapons, and beat up two staff members who were working overnight," writes Itar-Tass agency, citing a source in the republic`s emergency committee. "The workers were taken to hospital. One of them is in poor condition." Following the assault, the terrorists installed explosive devices in the turbine room. Two units were blown up by three explosions, which also set three floors of the turbine room ablaze. Several hours later - at about 09:00 Moscow time - firefighters managed to put the fire out. Later, sappers found and defused another bomb, preventing another blast. Russian Prime Minister Vladimir Putin has instructed deputy premier Igor Sechin to take all the necessary measures to restore the plant as soon as possible. The premier`s spokesman, Dmitry Peskov, said that Putin had also ordered Sechin to take emergency measures to make sure energy supplies were not disrupted after the blasts, writes RIA Novosti. Meanwhile, Russia`s National Antiterrorist Committee said that they have already ascertained those potentially responsible for the attack. "Government bodies are keeping the emergency situation in the area under their control," the committee said in a statement, writes Interfax. Also, the committee has called on people to assist in the detection of the militants responsible for the attack on the Baksan power plant.
