Moscow – Russian authorities believe a homemade bomb containing shrapnel is what exploded on an underground train in central St Peterburg on Monday, killing at least 10 people and wounding between 20 and 50 others, state media reported.
Another homemade bomb was found undetonated at a nearby station, and the blast is being investigated as a terrorist attack.
President Vladimir Putin was visiting the city, his home town, for talks with his Belarusian counterpart, Alexander Lukashenko. Putin offered his condolences to the victims’ families.
All underground stations in the city, Russia’s second largest, have been closed following the blast on a train at the central station Sennaya Ploshchad.
Thick smoke filled a part of the station, which was promptly evacuated. Some news reports said the blast occurred while the train was between stations.
