MOSCOW — Terrorism struck at the heart of Russia’s second-biggest city as a shrapnel-filled bomb tore through a subway train in St. Petersburg, killing 11 and wounding dozens more on a day when President Vladimir Putin was in his hometown for meetings.The bomb exploded while the train was traveling between two stations. Video footage shared on social media showed bodies strewn across a blood-splattered platform and panicked survivors clambering through a gaping hole in a subway car.
Investigators were working to “give a full picture of what happened,” said Mr. Putin, who was born in the city and who later placed a bouquet of roses at the subway station that was hit.
