Russian President Vladimir Putin has said the blasts on the St Petersburg Metro that killed at least 10 people could be a terror attack.
The Russian government is trying to establish the cause of the blasts and a terror attack would be considered 'first of all', he said in a statement.
"The causes of this event have not been determined yet, so it's too early to talk about [possible causes]," President Putin said. "The investigation will show. Certainly, we will consider all variants, common, criminal, first of all, of a terrorist nature."
President Putin was visiting St Petersburg, as deadly explosions injured scores of people and left almost a dozen dead.

Russia's National Anti-Terrorist Committee said 'several' people were killed and injured after an unidentified explosive device went off on a train that was travelling between two stations.
The committee confirmed that the metro is now 'basically' fully evacuated.
The explosion happened between the Sennaya Ploshchad station and Tekhnologichesky Institut at around 2:40pm local time.
