Moscow :(APS)April 3,2017-At least 11 people were killed and 50 injured when an explosion tore through a train carriage in the St Petersburg underground system on Monday, Russian authorities said.
Interfax news agency quoted an unnamed source as saying the blast was caused by a bomb filled with shrapnel.
Ambulances and fire engines descended on the concrete-and-glass Sennaya Ploshchad metro station. A helicopter hovered overhead as crowds gathered.
President Vladimir Putin, who was himself in St Petersburg for a meeting with Belarussian leader Alexander Lukashenko, said he was considering all possible causes for the blast, including terrorism.
A video showed injured people lying bleeding on a platform, some being treated by emergency services and fellow passengers. Others ran away from the platform amid clouds of smoke, some screaming or holding their hands to their faces.
A huge hole was blasted in the side of a carriage with metal wreckage strewn across the platform. Passengers were seen hammering at the windows of one closed carriage.
Russia has been the target of attacks by separatist Islamist Chechen militants in past years. Islamic State, which has drawn recruits from the ranks of Chechen rebels, has also threatened attacks across Russia in retaliation for Russian military intervention in Syria.
Russian airforce and special forces have been backing President Bashar al-Assad in fighting rebel groups and Islamic State fighters now being driven out of their Syrian strongholds.
A spokesman for Russia’s top anti-terror agency says law enforcement agents have found and defused another explosive device on St. Petersburg’s subway.
Andrei Przhezdomsky said the improvised explosive was found Monday on Ploshchad Vosstaniya station. He made the statement about two hours after a blast on a subway train in St. Petersburg killed at least 10 and wounded dozens of others.
