Security increased in Moscow and elsewhere after more than 30 are killed in deadly blasts just weeks before the start of the Sochi Olympics.
A second terrorist attack in as many days in the southern Russian city of Volgograd has raised fears that Islamist militants are coordinating bombings as the country prepares to host the 2014 Winter Olympic Games in Sochi.
Monday’s attack claimed 14 lives and injured dozens more after an explosive device planted on a trolleybus detonated during rush hour near the city center, officials said.
The explosion came less than 24 hours after a blast at the entrance of the city’s central railway station killed 17 and critically injuring more than 40 on December 29 in what authorities said was a suicide bombing.
“Now we can say that the bomb was detonated by a suicide bomber, a man. Fragments of his body had been recovered and sent to genetic examination to establish his identity,” Investigative Committee spokesman Vladimir Markin said. The two explosions are most likely interrelated, he added.
According to Markin, the power of the explosive device was at least four kilograms of TNT.
“Like the bomb at the railway station, it was packed with shrapnel. Since the strike elements are identical in the two bombs, it confirms the version of our investigation saying that the two attacks are related to each other. Perhaps they could be prepared in one place,” Markin said.
According to most recent data, the suicide attack in Volgograd on December 30 killed 14 people, 28 were hospitalized, said Markin. Law-enforcement agencies strengthen security measures in the entire Volga Federal District, as well as in other regions of the country, including Moscow.
