On March 9, 2011 an unidentified device exploded in snow at the stop on Michurinsky Avenue around 1630 (1330 GMT). Two or three cars and the bus stop itself were damaged. The explosion had occurred opposite No 70 Michurinsky Avenue – the FSB academy is located at No 90.
On March 11, twin blasts rocked northern Moscow. The two bombs – one left on top of an outdoor garage and the other left in a metal garbage container — went off outside a building housing FSB employees and their families. “The blasts went off one after the other,” Interfax quoted a police spokesman as saying. “Each bomb had the blast equivalent of about 150 grammes of TNT.”
Nails packed with the explosives shattered glass across seven floors of the high-rise building, with the head of the Moscow FSB’s investigative unit heading out to the site to personally inspect the damage, RIA Novosti reported.
Police sources said the explosives were similar to the small bomb that went off on Wednesday outside a bus stop near the FSB Academy in Moscow.
Wednesday’s blast has been claimed by the Riyadus Salikhin Martyrs Brigade, an Islamist group founded by the Chechen warlord Shamil Basayev before his violent death in 2006. The groups said in a statement posted on the Kavkazcenter.com website popular with Islamists that Wednesday’s attack was carried out in reprisal for past FSB operations in the Caucasus. “We intend to continue striking facilities and places where the (FSB) criminals gather,” the statement said.
On Monday, March 14, it became known that all FSB buildings in Moscow are placed under security to prevent further attacks.
At the same time the police seemed not to buy the claims made by islamists. A police official told Interfax that chemistry students with ultranationalist views may be behind a string of bombings targeting Federal Security Service buildings in Moscow. The choice of targets, the lack of any victims, and the way the bombs were made suggest that students are the prime suspects, not professional terrorists, the unidentified official said. He added that the bomb makers were not likely to be members of organized ultranationalist groups.
The last time FSB facilities came under attack was back in 1998-1999. On 13 August 1998 the lobby of the FSB on Lubyanka was blown up, slightly injuring two FSB guards.
On 3 April 1999 a second attack occurred at almost exactly the same place when a bomb containing the equivalent of 1.5 kilos of TNT was detonated, although this time nobody was killed or wounded).
Both bombings turned out to have been carried out by left-wing extremists from the group called “New Revolutionary Initiative”, which actually consisted of four idealistic young women in their 20s inspired by the German Rote Armee Fraktion (Red Army Fraction): Nadezhda Raks, Olga Nevskaya, Tatiana Nekhorosheva-Sokolova and Larisa Romanova. The group was identified soon after the first explosion, but the Moscow department of the FSB preferred to keep the group under surveillance rather to prevent the second bombing.
At trial the FSB claimed it had discovered a powerful terrorist organization of nearly 500 members which intended to overthrow the political regime. All the defendants were found guilty in terrorism: Olga Nevskaya was sentenced to 6 years, Larisa Romanova to 6.5 years and Nadezhda Raks to 9.5 years’ imprisonment.
