Video: 11 people killed and 50 injured in St Petersburg metro attack by suicide bomber, second bomb found and defused
At least 11 people are reported to have been killed by the blast and 50 including children have been injured. Nobody has claimed responsibility, but previous attacks on Russia have been blamed on ISIS and Chechens. A bearded man who was identified on CCTV as the main suspect has handed himself and insists he is innocent. Russian detectives now believe a suicide bomber with links to radical Islamists was behind the horrific attack.
