Eleven people were killed in a blast on the St. Petersburg metro on Monday, the Russian health ministry said, in what authorities described as a terrorist attack.

An explosion tore through a train as it was traveling between two stations in Russia's second-biggest city, injuring dozens more.
A second device was found and defused at another station, Russia's Anti-terrorist Committee said. No group has so far claimed responsibility for the attack, which led to the shutdown of the entire metro system in St. Petersburg.
