A 17-year-old has died of his wounds after detonating explosives in an office of Russia’s FSB federal security service in the north-western city of Arkhangelsk, officials say.
Three FSB employees were hurt when the explosives went off just inside the building at around 09:00 (06:00 GMT). The blast caused serious damage.
A CCTV image of the suspect emerged soon afterwards, along with a message he allegedly posted on social media just before the blast.
Although the authenticity of the message posted on an anarchist chat group has not been confirmed, the user identifies himself as an anarcho-communist and claims the FSB “fabricates cases and tortures people”.
Russia’s anti-terrorism committee said, according to initial findings, the suspect was a 17-year-old local resident who had gone into the building and pulled out of his bag an “unidentified object that exploded in his hands”.
