This footage taken from a dashboard camera shows a bus carrying about 40 people being blown up by an alleged female suicide bomber in the Russian city of Volgograd. At least six people have been killed, and as many as 30 injured, some critically.
A driver behind the bus told Rossiya-24 television: "There was a blast — a bang — all the glass flew out of the windows. The cloud of smoke quickly dissipated and then I saw people start to fall out and run out to escape the bus. It was a horrible sight."
According to authorities, the suspect is Naida Asiyalova, 30, who was married to an Islamist rebel commander, Dmitry 'Giraffe' Sokolov in the highly volatile region of Dagestan.
According to an Investigative Committee spokesman, "This woman, in a hijab, got on the bus at one of the stops and the explosion occurred almost immediately afterwards." A 20-month-old toddler was reportedly injured in the blast.
Asiyalova's husband Sokolov, now known as Abdul Jaffer, is wanted in Dagestan for his role in two terrorist explosions, according to state media.
According to information obtained by LifeNews from security sources, the suicide bomber, Asiyalova, earlier recruited a young Muscovite, Dmitry Sokolov, who became a skilled bomber respected by Islamist militants. The 22-year-old reportedly fell in love with the female recruiter while studying Arabic in a Moscow university. She then turned him to radical Islam and convinced him to leave home for Makhachkala.
Unconfirmed reports also said she was ill with a serious and possibly terminal bone disease.
Asiyalova was from Dagestan in the volatile North Caucasus region which has seen many attacks in recent years. The bombing has now raised fears about militant attacks leading up to the 2014 Winter Olympics in Sochi, not very far from North Caucasus.
