Nikolai Patrushev, director of federal security service at the National Anti-Terror Committee, said the Volgograd water reservoir, the Tsimlyanskoye hydropower project, hydropower stations in the Saratov Region and the Dagestan Republic are among those targeted in the plot, reports the Itar-Tass news agency.
He did not give other details.
"It is necessary to stress that this threat is quite real," Patrushev said. "The results of the examination of terror threats enabled us to draw the conclusion that if saboteur acts are carried out at one of hydro-technical facilities, disastrous aftermaths can take place, including a paralysis of life of an entire district, numerous losses of human life, serious economic consequences, etc."
The NAK chief said the current systems in place to protect these facilities are not adequate.
