(FOX NEWS) — By Mike Arroyo
One person was believed to be behind the deadly attack in the subway in St. Petersburg, Russia, planting two bombs, one of which exploded, state media reported Monday.
At least 11 people were killed and some 45 others were wounded. Police initially believed a suicide bomber planted the device that exploded on a train, while a second person planted a separate device at a nearby station — but investigators later said it appeared to be the work of one man, the Interfax news agency reported. Crews disabled the second device before it could explode.
Both bombs were filled with shrapnel, according to Sky News. The unexploded device was rigged with up to 2.2 pounds of explosives, Interfax added.
Russian President Vladimir Putin said investigators were looking into all possible causes. President Trump called it “absolutely a terrible thing,” adding, “it’s happening all over the world.”
The 2:20 p.m. explosion rocked the train between the Technology Institute station and the Sennaya Square station, Russia’s National Anti-Terrorist Committee said. Photos and video from one station appeared to show wounded victims on the smoke-filled platform, and a train car with a door blown out. Frantic commuters reached out through the doors and windows, shouting, “Call an ambulance!”
Nobody immediately claimed responsibility for the blast. The National Anti-Terrorism Committee reported late Monday an 11th person had died.
“People were bleeding, their hair burned,” a witness told Russia’s Life News. “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.”
Russian media, The Associated Press and other news agencies sent out a photo of a bearded man dressed in black, initially claiming he was wanted in connection with the blast. Interfax later reported that the man went to police to claim he was innocent.
Trains and train stations have been common targets for terrorist attacks in Russia and throughout much of Europe, analysts point out.
