A female suicide bomber blew herself up at a railway station in southern Russia on Sunday, killing at least 14 people, authorities said.
Dozens of others were injured in the explosion, which occurred at 12:45 p.m. Moscow time (0845 GMT) in Volgograd, a city near the volatile North Caucasus region, regional law enforcement agencies told local media.
The suicide bomber detonated her explosives in front of the metal detection arches inside the main entrance to the railway station, local media reported.
Police are currently investigating the blast on-site.
Live TV footage showed the railway station was cordoned off and ringed with ambulances and police cars.
A video clip aired by the Russiya-24 TV channel recorded the moment of the blast. The main building of the railway station was suddenly rocked by a powerful explosion inside, with heavy smokes spewing from the entrance following a sparkling flame.
