The blast occurred Tuesday on a train traveling through a tunnel from Sennaya Square to the Technological Institute in St Petersburg. The current suspect is Akbarjon Djalilov, born in 1995, a Kyrgyz national who recently obtained Russian citizenship.

Turkish President Recep Tayyip Erdogan on Tuesday sent Russian President Vladimir Putin a letter of condolence which strongly condemned this attack.
