8 arrested for St Petersburg bombing

Alexander Bortnikov, chief of the FSB, the main successor to the KGB intelligence agency, said yesterday that six members of terror cells were detained in St Petersburg and two in Moscow in connection with the attack. Bortnikov said all of them hail from former Soviet Central Asian republics and that the police found a large amount of weapons and ammunition at their homes, adding, "The investigation showed that the operative work did not fully meet the threat from terrorist organisations".
