The FSB Public Relations Center added that 187 Russian citizens were arrested on suspicion of belonging to the Columbine extremist movement and the Ukrainian group known as Maniacs Cult of Murder.

Some of the detainees had stabbing weapons in their possession, means for the dissemination of materials on the Internet to carry out terrorist actions and of extremist nature, the agency further said.

The arrested also had documents of their relation with ideologues promoting massacres and with members of Ukrainian nationalist armed groups.

Videos and photos of the “direct actions” of these groups were also seized, as well as instructions to carry out mass murders with the use of homemade bombs and flammable devices against government centers and education and transportation infrastructure.

The Columbine High School massacre, which took place in April 1999 in the United States, became a cult act for promoters of Internet violence, with followers in several countries, including Russia, where several cases have already been registered, which are seen as an attempt to imitate the Columbine killers.
