ST. PETERSBURG, Russia (AP) - Russian officials say a bomb explosion on railroad tracks in St. Petersburg injured one worker and is being considered a terrorist attack.
Russian Railways says in a statement that the pre-dawn explosion Tuesday hit a small maintenance locomotive on the outskirts of the city. The driver suffered a leg injury. The blast caused the disruption of commuter rail traffic for several hours.
The Interfax news agency cited Anatoly Kvashnin, head of the regional transport investigation service, as saying "We are considering this as a terrorist act, that's the main theory."
In December, 27 people died when a bomb blast derailed a high-speed train bound from Moscow to St. Petersburg.
