A video of the aftermath of an explosion which went off in the Russian Federal Security Service (FSB) building in the northwestern city of Arkhangelsk, has been published.
The footage showed a street in Arkhangelsk where the explosion occurred, with ambulance and fire-fighting vehicles having arrived at the scene. Also, rescue workers and police officers are seen near the entrance to the FSB building where what looks like the body of the perpetrator of the blast is also seen.
At least one person was killed (in addition to the attacker) and three more were injured in an explosion that ripped through Arkhangelsk's FSB building earlier on Wednesday, the region's governor Igor Orlov said.
