(Volgograd) – At least 14 people were killed when a suicide bomber blew himself up on a packed trolleybus in Volgograd, raising new concerns about security at the Sochi Olympics a day after a deadly attack on the southern Russian city’s train station.
President Vladimir Putin ordered stepped-up security across the country after the trolleybus bombing at the peak of the morning rush and Sunday’s suicide attack blamed on a suspected female suicide bomber which claimed 17 lives.
