Russia's Federal Security Service (FSB) announced on Wednesday it had prevented terror attacks planned by an Islamic State group in the Moscow region.

"Russia's FSB has thwarted activities of a cross-regional IS cell, participants of which intended to conduct subversive terror attacks in the Moscow region," the FSB said in a press release.

Security officers have detained one person, who is a citizen of a Central Asian country, in the Vladimir region, and seized a home-made bomb.

The FSB said that an improvised explosive device filled with destructive agents and some other items and documents were retrieved.

An investigation is underway.
