At approximately 14:01 on 21 October 2013, Naida Sirazhudinovna Asiyalova (), a 30-year-old fugitive from the
Republic of Dagestan, boarded a bus in the Krasnoarmeysky district of Volgograd. The passengers on this bus were predominantly students in their late teens and early twenties returning home from classes at
Volgograd State University. According to
eyewitnesses, Asiyalova boarded the bus in Volgograd city centre, taking a seat towards the rear of the vehicle and silently looking out of the window as the bus made two further stops before detonating her suicide belt at 14:05, killing herself and seven others and injuring 41—several severely.
Investigation No individuals or terrorist organization claimed responsibility for the attack. Although initial reports speculated the explosion had been caused by an "unidentified explosive device", possibly a gas leak, eyewitness testimony and
physical evidence recovered from the site of the explosion enabled investigators to quickly determine the blast had been caused by a female suicide bomber wearing a green
hijab who, according to one survivor, had been "looking out the window, acting calm [and] not drawing any attention to herself" immediately before detonating her device. An identity card recovered within the bus confirmed the identity of the suicide bomber as 30-year-old Naida Asiyalova and within hours of the explosion, a spokesman for the
Investigative Committee of Russia named her husband, Dmitry Sokolov, as a prime suspect in the attack. The explosive device consisted of two blocks of
TNT weighing between 500 and 600 grams and two grenades (one of which failed to detonate in the explosion). In addition, Asiyalova had numerous shards of metal, screws, and
bolts on her possession to maximize the devastation of the blast. Although one grenade had exploded when Asiyalova detonated her suicide belt, one unexploded grenade was discovered beneath the bus. As Asiyalova was found to have a ticket to travel to the capital on her possession at the time of the explosion, investigators believe the suicide attack was originally intended to take place at an unknown location in Moscow, although for unknown reasons, Asiyalova chose to detonate her device upon the bus. On the evening of the bombing, authorities within the
Volgograd Oblast declared three days of mourning, commencing 22 October. The same day, the
People's Republic of China condemned the bombing. ==Perpetrators==
