Second bomb in 2 days hits Russian city, 14 dead

At least 14 people have been killed in a bus explosion in Volgograd Monday, a day after a suicide bombing that killed at least 17 at a railway station in the city.
The explosions put the city on edge and highlighted the terrorist threat that Russia is facing as it prepares to host the Winter Games in February. Volgograd is about 400 miles northeast of Sochi, where the Olympics are to be held.
