A suicide bombing has killed at least 14 people and injured over 40 in the southern Russian city of Volgograd, raising concerns about terrorism just over a month before Russia hosts the 2014 Winter Olympic Games.

A female bomber carried out the blast in a Volgograd train station, 400 miles from the site of the upcoming Olympics in the Russian resort town of Sochi, Russian authorities said. The Sochi 2014 Olympic Games are scheduled to begin on Feb. 7.

A total of 33 people were hospitalized, with eight in serious condition and one in "extremely serious condition," Oleg Solagai, a spokesman for the Russian health ministry, told Russian news agency Rossiya24.
