An explosion on a subway train in the Russian city of St. Petersburg killed 10 people on Monday afternoon, according to the Tass and Interfax news agencies.
The subway’s administration said several stations in the northern city have been closed and that an evacuation was underway.
Social media users posted photographs from one subway station in the city centre that show people lying on the floor and a train with a mangled door nearby.
Russian news agencies quoted Kremlin spokesman Dmitry Peskov as saying Russian President Vladimir Putin has been informed about the explosion. Putin is visiting the city Monday and is expected to hold talks with the president of Belarus later in the day.
The cause of the blast was not immediately clear.
Putin offered his condolences to the victims’ families.
