A Russia Today TV news clip about the apparent terrorist attack
Russia's Federal Security Service (FSB) confirmed today that a 4.5 pound bomb exploded on an express train between Moscow and St. Petersburg last night. The explosion happened at 10:43 p.m. local time while the train was travelling through the Novgorod region approximately 310 miles north of Moscow. The blast was powerful enough to derail twelve passengers cars and one locomotive. At least sixty people were seriously injured as a result of the attack.
Russian prosecutors believe that at least one of the suspects may have been captured on video surveillance footage. After diverting more than fifty trains following the attack, Russian Railways repaired the damaged section of track today and resumed regular train service between Moscow and St. Petersburg this evening.
