MOSCOW (AP) - Russian security forces are looking for the husband of a suicide bomber who attacked a bus in southern Russia yesterday, killing six people and wounding more than 30.
Investigators say the 30-year-old woman was from the volatile province of Dagestan in Russia's North Caucasus region, and was married to an ethnic Russian man who had joined Islamic militants. They say her husband had become a top rebel expert in explosives, and that he could have been involved in equipping his wife for her suicide mission.
According to investigators, he has been on the run since he left his home in a Moscow suburb in 2012.
The bombing in the southern Volgograd region was the first attack against a civilian target outside the North Caucasus region in years. It's raising fears of a new wave of terror, just three and a-half months before the start of the 2014 Winter Games in Sochi.
Authorities are trying to determine whether the woman had initially planned to attack in Moscow. They say she was on a bus to the capital, but got off in Volgograd and took a local bus, where she detonated her explosives.
