MOSCOW (AP) - A number of details remain unclear, but at least 16 people are dead and scores more wounded after a suicide bombing at a railway station in southern Russia.
The casualties include the bomber, who officials initially said was a woman. But the Interfax news agency later quoted law enforcement agents as saying that surveillance footage indicated that the bomber was a man.
The attack took place in Volgograd, which lies close to the volatile Caucasus provinces.
No one immediately claimed responsibility for the bombing, but it comes several months after a Chechen rebel leader (Doku Umarov) called for new attacks against civilian targets in Russia, including the Winter Olympics set for February in Sochi.
Russia has been hit by suicide bombings for years, but most have been in the North Caucasus, the center of an insurgency seeking an Islamist state in the region.
Until recently Volgograd was not a typical target, but the transportation hub has now been struck twice in two months.
