Video of the carnage left after the explosion

Second unexploded bomb found disguised as a fire extinguisher was discovered at a second St Petersburg subway station

Russian media outlets released pictures of the bearded suspect who is wearing a long, black top and a hat and is thought to have caused carnage by detonating the bomb which sent shrapnel shredding through the train.
Dozens have been injured, including children, as it was reported the man left a briefcase on a train before moving carriages moments before the deadly blast and a second explosive device was found and defused in a nearby station.
Bloodied passengers were left strewn across the platform in the Russian city as emergency services scrambled to save those wounded by the bomb and the resulting shards of glass and twisted metal.
Russian president Vladimir Putin was already in his hometown of St Petersburg today for talks with the president of Belarus and confirmed ‘there are dead and injured’, offering his condolences to the families of those killed.

The Kremlin leader, who wanted to visit the scene in the aftermath of the attack but was held back by security services, said: ‘I have already spoken to the head of our special services, they are working to ascertain the cause of the blasts. Kremlin spokesman Dmitry Peskov however, denied earlier speculation that President Putin was due to pass by the Sennaya Metro station around the time of the blast.
‘The causes are not clear, it’s too early. We will look at all possible causes, terrorism as well as common crime.’
Interfax news agency is citing an unidentified source who says the suspect in Monday’s blast might have left the explosive device in a bag.
The explosion happened between the Sennaya Ploshchad station and Tekhnologichesky Institut at around 2.40pm local time, Russia’s National Anti-Terrorism Committee said.
Earlier reports indicated a backpack had been thrown onto the train and witnesses also suggested there had been multiple explosions, but officials confirmed just the one blast.
Russian security agencies did find an explosive device at a different metro station in central St Petersburg and made it safe, the National Anti-Terrorist Committee said in a statement.
The device was found at the Ploshchad Vosstaniya metro station, a different location from where a blast earlier took place.
Other witnesses also described a man leaving a briefcase on one carriage before moving to another just seconds before the huge explosion.

As reports of the suspected terror attack hit Moscow, the capital city heightened its security and local while reports suggest three metro stations – Nagatinskaja, Savelovskaya and Ugrezhskaya were cordoned off due to suspicious packages.

‘My girlfriend was in the next car that exploded. She said that he began to shake. When she came out, she saw that people were mutilated.’
Eight bodies were recovered from the carriage while two more were found on the platform and the final two killed were found in the tunnel.

A male eyewitness said: ‘It’s just like a war here. Every special service is here, the FSB, police, and multiple – really a lot of them – ambulances.
‘I don’t think I’ve ever seen to many paramedics in my life. Something completely horrible is happening here.’
The Life News website showed pictures of blown-out train doors and several injured people on the station platform.
