The video, made public by the security service this Monday, shows an entry team surround and handcuff one of the men – said to be a Russian citizen – in the stairwell of a multi-storey building. The camera then jumps to the moment his flat was thoroughly searched, uncovering a cache of shotgun cartridges, combat knives and electric wires. 

His accomplice, also a Russian national, appears on another video while presumably pledging allegiance to Islamic State (IS, formerly ISIS) in Arabic.
The FSB didn’t expand much on the arrests, but said it secured enough evidence proving the suspects were planning to carry out terrorist attacks in St. Petersburg.
