MAKHACHKALA, Russia (AP) — Russian security forces on Wednesday killed a militant who may have helped to train the two suicide bombers who struck the southern city of Volgograd, investigators said.
The bombings of a train station and an electric trolleybus in late December killed 34 people and heightened security fears ahead of the Sochi Winter Olympics, which begin on Friday.
Russian law enforcement agencies have announced a series of developments in the case in recent days, including the identification of the suspected bombers and the arrests of two suspected accomplices.
Security forces on Wednesday surrounded a group of militants who had holed up in the Dagestani town of Izberbash, said Rasul Temirbekov, a spokesman for the Investigative Committee, a federal agency.
In an exchange of gunfire, security forces killed 30-year-old Dzhamaldin Mirzayev, who was suspected of having been involved in training the bombers and sending them to Volgograd, Temirbekov said.
