At least 10 people were killed and 20 injured when an explosion tore through a train carriage in the St.Petersburg metro system on Monday, Russian authorities said. Ivor Bennett reports.
The force of the explosion was instantly clear. A set of doors replaced by twisted metal and a gaping hole. As survivors hammer on the windows of the train to help anyone trapped inside. At least 10 people were killed in the explosion on the St. Petersburg metro. At least 20 more injured, in what authorities have called a probable terrorist attack. Russia's Interfax news agency said the blast may have been caused by a device concealed in a briefcase. Police are reportedly searching for a man caught on CCTV. It happened in the early afternoon. At the Sennaya Ploschad station near the centre of Russia's old Imperial capital. Emergency services swarmed the road above. Including a helicopter landing just metres from parked cars. And an endless stream of fire crews and ambulances to treat the wounded. Initial reports were of two explosions. It was later confirmed to be one, in a tunnel in between stops. But Russia's investigators said another explosive device was discovered and diffused at a separate station. Russian President Vladimir Putin was in the city at the time, meeting the leader of Belarus. His response so far has been cautious. Investigators have said they will consider all possible causes. Russia has been the target of attacks by Chechen separatists in the past. Islamic State has also threatened attacks in retaliation for Russian military intervention in Syria.
