At least 10 people are reported to have been killed in Russia’s St Petersburg metro explosion. Three stations have been closed, according to local media outlet Fontanka.
News agencies Tass and Interfax reported that the blasts hit the Sennaya Ploshchad and nearby Institute of Technology stations in the centre of the city.
Quoting local media reports, BBC reported that Russian President Vladimir Putin, who is in the city, had been informed.
A Sky News report said that at least one of the devices was filled with shrapnel.
The St Petersburg underground railway said in a statement: “An evacuation from the stations is ongoing, there are people injured. An unidentified object supposedly blew up in a (train) carriage.”
Putin was expected to visit St Petersburg on Monday.
