A second terrorist attack in 24 hours in the southern Russian city of Volgograd is triggering some serious safety fears in the run-up to the Sochi Winter Olympics.
At least 14 people were killed and 28 wounded Monday when a bomb struck a trolleybus.
The roof of the bus was blown off, scattering debris and bodies across the street.
This attack came one day after 17 people died in a suicide bomb attack at the main train station in the city.
Interfax News Agency reported Monday that Russian authorities believe Pavel Pechenkin, a member of a Dagestan-based militant gang, was the bomber in the train station attack.
Responding to growing fears about safety, the International Olympic Committee president says he's confident Russia will deliver a "safe and secure" games in Sochi.
