The Russian Federal Security Service (FSB) has targeted eight residents in the republic of Ingushetia, who it claims were preparing terrorist attacks against energy infrastructure and police officers.
Security was ramped up across Muslim-majority regions in southern Russia, including Ingushetia, following a deadly gun attack in Dagestan in the summer.
The agency raided several addresses in the cities of Magas and Nazran, it announced in a statement on Monday. A suspect at one location was shot after resisting arrest, according to a report and accompanying footage and images released by the FSB.
The video also included the moment an alleged secret weapons stash in a wall was discovered. The arsenal included a shoulder-fired grenade launcher, 11 hand grenades, five assault rifles, nine handguns, and a massive improvised explosive device with an equivalent yield of 10kg of TNT, the FSB stated.
The suspects have been charged with crimes related to illegal possession of explosives and weapons, and attempted sabotage.
Last month, security officials in Ingushetia reported that they had foiled a gun attack on a church in the region, which would have mirrored the high-profile terrorist assault in Dagestan in June.
On that occasion, a coordinated attack in two cities resulted in gunmen killing 22 people, including a Christian priest, a synagogue security guard, and 17 police officers.
