On Monday, an explosive device detonated on a train as it traveled between two St. Petersburg metro stations. According to Russian officials, at least ten people have been killed in the St. Petersburg subway explosion. Russia's National Anti-Terror Committee, said the explosive device, which Bloomberg described as a "makeshift bomb filled with shrapnel," detonated at 2:40 pm local time as the train was traveling through St. Petersburg's city center. According to Bloomberg, Interfax reported that the explosive device was not detonated by a suicide bomber but, rather, left on the train.
NBC News reported that Andrei Kibitov, the press secretary for the St. Petersburg governor, said there were around 50 people injured, but that number has yet to be confirmed.
Russian President Vladimir Putin was in St. Petersburg on Monday to, among other things, meet with Belarausian President Alexander Lukashenko. Putin said there was not enough information yet to determine whether the explosion was a terrorist attack. "The causes are not clear, it's too early. We will look at all possible causes, terrorism as well as common crime," Putin said.
However, other Russian officials were quicker to suggest the incident may be an act of terrorism. Viktor Ozerov, who leads the security committee in the upper house of parliament, said "All the signs of a terrorist attack are there," added that "the complex of measures against terrorism in the country failed."
While much is still unknown about the deadly incident, there are photos and videos from the scene that are providing some sense of the situation.
CNN shared photos of the smoky aftermath from the explosion. "I think that explosion happened in the tunnel between the stations. The smoke was coming out of there. There was nothing on the station itself, everything was fine," Stanislav Listyev, a passenger at the Sennaya square station, said.
Bloomberg shared photos of Russian authorities cordoning off the area around the explosion as crowds gathered.
Fox News reported that one witness to the explosion told Russia's Life News:
People were bleeding, their hair burned. 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.
NBC News shared photos of what appeared to be victims of the blast, which occurred as the trian traveled between the Sennaya Ploschad and Tekhnologichesky Institute subway stations. "Images circulated on social media showing a mangled train car, bodies lying on the ground and emergency vehicles parked outside what appeared to be an entrance to the station," NBC noted, but added that, "None of these images have been verified."
The Guardian shared an amateur video of passengers pouring out of a subway car at the smoke-filled Sennaya Ploshchad station.
CNN also shared video of a mangled train and people appearing to rush to get out of it. Around 5 million people live in St. Petersburg, and more than 2.3 million people ride the city's subway each day, according to CNN.
The U.S. Embassy in Russia tweeted shortly after the explosion, "We are shocked and saddened from the blast in St. Petersburg, as the result of which people died and were injured. We wholeheartedly support the victims and their families."
