A part of al-Qaida, Istambuli Brigade accepted responsibility for blowing up TU-154 and TU-134 planes. The explosive device applied near the Metro Station was similar to that used for exploding the bus stop on Kashirskoe Highway. The investigators do not rule out a version that the explosion near the Metro is directly linked with the terrorist acts at the two planes, and the explosion on Kashirskoe Highway. The investigation has information on 4 female martyrs-suicide bombers who stayed in Moscow. Previously PRAVDA.Ru wrote that after the two martyrs blew themselves up on the planes, the other two stayed in Moscow. Now one of them probably blew herself up as well.
According to the preliminary information, the name of the terrorist who made the explosion near RIzhskaya Metro Station, is Roza Nogaeva – the sister of Amanat Nogaeva, who is suspected of exploding TU-134 plane.
According to one version, the explosives were put under VAZ-2107 vehicle, but there is another version that the belt with explosives blew up on the female terrorist in front of the entrance to the Metro Station.
