Ten people have reportedly been killed after a bomb blast on the metro system in the Russian city of St Petersburg.

Eyewitnesses say an explosion took place amid reports of bombings.
A total of 50 people are also thought to be injured, including children.

“There was a deafening bang, then the sharp smell of smoke. We immediately went to the end of the car, formed a crush.”
Speaking to Life News, one witness said: “People were bleeding, their hair burned.
“We were told to move to the exit. People just fled.
“My girlfriend was in the next car that exploded. When she came out, she saw that people were mutilated.”
“One eyewitness wrote on Twitter: “I was riding down the escalator and suddenly an explosive wave from below, echoing from the tunnel. The station is evacuated. ”
Maxim Liksutov, Moscow’s deputy mayor, told Interfax that authorities were tightening security on the subway in the Russian capital.
The agency that runs the subway said several stations in the northern Russian city were closed and that an evacuation was under way.
Social media users posted photographs and video from a subway station in the city centre, showing people lying on the floor outside a train with a mangled door.
Frantic commuters reached into doors and windows, trying to see if anyone was there and shouting: “Call an ambulance!”
