"According to our information, the explosion was carried out by a female suicide bomber who approached a metal detector, saw a policeman there, got nervous and detonated the bomb stuffed with pieces of shrapnel," said Mr Markin. He said that initial information suggested the bomber "approached a metal detector, saw a policeman there, got nervous and detonated the bomb stuffed with pieces of shrapnel".
He said the security presence had prevented a much higher death toll at the station, which was packed at the time of the blast as several trains were delayed.He said the security presence had prevented a much higher death toll at the station, which was packed at the time of the blast as several trains were delayed.
RIA Novosti news agency said security sources were naming the attacker as Oksana Aslanova. She has reportedly been married twice to militants and is also suspected of being a friend of Naida Asiyalova, the suicide bomber who targeted the Volgograd bus in October. Mr Markin was among officials suggesting early on that the bomber was a woman - with RIA Novosti news agency naming the attacker as a Dagestani woman, Oksana Aslanova, and other new outlets publishing pictures of what they said was the severed head of the female bomber.
However, the Interfax news agency later quoted an unidentified security source as saying "it has been established that the suicide terrorist was a man who had brought explosives to the station in a rucksack. But investigators' initial certainty was replaced with uncertainty, with suggestions the bomber could have been a man or that there could have been multiple bombers, our correspondent says.
"His identity has been established," the source said, though he did not give details.
The agency said the suspect's head had been found at the site.
