Russian authorities say they have detained six individuals in the North Caucasus for alleged links to the Islamic State (IS) militant group.
Federal Security Service (FSB) officials in Karachayevo-Cherkesia said on October 20 that the six were detained after investigators found assault rifles, ammunition, camouflage outfits, and explosives in a house.
Authorities said they also discovered video recordings of the suspects taking an oath of allegiance to the IS extremist group.
The suspects -- described as residents of the Karachayevo-Cherkesia, Daghestan, and Stavropol regions -- face terrorism charges.
Russian officials say at least 5,000 Russians and citizens of other former Soviet republics have traveled to Syria and Iraq to join IS extremists.
