Second Volgograd blast 'was suicide bombing'

A blast that tore through an electric bus in the southern Russian city of Volgograd during Monday’s morning rush hour, killing 14, was probably carried out by suicide bombers from the same organisation behind a railway explosion a day earlier, officials said.

Together more than 30 people were killed in the explosions, putting the city of one million on edge and highlighting the terrorist threat Russia is facing as it prepares to host February’s Winter Olympic Games in Sochi, President Vladimir Putin’s pet project. While terrorists may find it hard to get to the tightly guarded Olympic facilities, the bombings have shown they can hit civilian targets elsewhere in Russia with shocking ease.
