An explosion Monday on a subway train in St. Petersburg, Russia, killed at least 10 and injured dozens more. The attack happened as Russian President Vladimir Putin was in the city to meet with President Alexander Lukashenko of Belarus. The explosion hit the subway train as it traveled between stations. The train’s driver chose to continue on to the next station, Technology Institute. That might have saved lives. By moving the train to the next station the driver made it easier to remove injured passengers, said an official with Russia’s Investigative Committee. It also took away the possibility of injury, or even death, if passengers were to have walked along the subway system’s electrified tracks, the official said. Russian officials later found and disabled another bomb at the city’s Vosstaniya station.
