A nail bomb thrown onto a train by a suspected terrorist has ripped through a carriage in St Petersburg killing at least 12 people and injuring 50 more today.
The terrifying incident, which is being investigated as a terror attack, took place on a train that was travelling between Sennaya Ploshchad and Sadovaya metro stations.
The attack has left dozens injured, including children, and witnesses described seeing a man throwing a backpack onto the train moments before the explosion and a second explosive device was found and made safe in a nearby station.
20 years ago, one would assume Chechens. Now, given all the insane war drums beating, it could be anyone from Ukrainians to the CIA.
