VOLGOGRAD, Russia — Russian security forces hunted on Tuesday for the husband of a bomber who blew herself up on a bus in southern Russia, killing six people and wounding more than 30. They also raised the possibility that Moscow, not Volgograd, was the bomber’s original target.
Adding to the mystery surrounding Monday’s explosion, Russian state television released pictures of the attacker’s passport that looked different, even though they carried the same number.
Investigators said 30-year-old Naida Asiyalova, a native of the volatile province of Dagestan in Russia’s North Caucasus region, was married to an ethnic Russian man who had joined Islamic militants. They said her husband, Dmitry Sokolov, has become a top rebel expert in explosives and could have been involved in equipping his wife for the suicide mission. Sokolov has been on the run since he left his home in a Moscow suburb in 2012, according to the investigators.
The bombing was the first attack against a civilian target outside the volatile North Caucasus region in years.
