Russia’s Federal Security Service (FSB) has detained 13 members of a closed online community who plotted mass killings, the FSB said in a statement, APA reports citing TASS.
Four improvised explosive devices, components for making petrol bombs, as well as hunting, non-lethal and bladed weapons were seized. The group consisted of young people.
"Personal diaries and communication means seized from these people prove that they had plans to commit crimes. The diaries particularly contain bomb-making manuals and blueprints of attacks on educational and law enforcement facilities, as well as on public places," the FSB added.
"The necessary procedural steps and preventive measures will be taken after tests are conducted," the FSB said.
