The Russian city of Volgograd was rocked by two suicide bombings in less than 24 hours.
At least 14 people were killed Monday when a suicide bomber set off a blast aboard a packed commuter bus around 8:10 a.m. local time. In addition to the dead, 28 were injured by the blast. Investigative Committee spokesman Vladimir Markin believes Monday's bus attack is linked to Sunday's suicide bombing at the Volgograd-1 railway station. Monday's deadly bus attack comes a day after a female suicide bomber detonated herself on at the city's central train station around 12:45 p.m., killing seventeen people.
