Russian investigators say the woman who detonated explosives on a Volgograd bus on October 21 may have intended to attack a shopping center in the city instead.
A spokesman for the Russian Investigative Committee, Vladimir Markin, said the bomber, who was identified as Naida Asiyalova from Daghestan, was in the Akvarel shopping center for a few minutes but that there were only a few people present and she suddenly left for a bus stop.
About 30 minutes later there was an explosion on the city bus that Asiyalova boarded that killed six people and wounded more than 50 others.
Markin also said Asiyalova seemed to have acted alone in the Volgograd attack, but investigators are looking into possible accomplices she might have had in Daghestan.
Asiyalova's husband, a wanted militant, is believed to be in Daghestan.
