The Russian security agency said today it found weapons and explosives after raiding a string of locations in central Russia to shut down an online group spreading propaganda for ISIS terrorists.
The FSB security service and the police "identified and thwarted" the activities of cells belonging to an international internet community "created for the propaganda of terrorist ideology and recruiting of fighters for the ISIS", the FSB said in a statement.
The cells were based in Russia's central Sverdlovsk, Tyumen and Chelyabinsk regions, where the FSB said it conducted 27 searches on Wednesday at the homes of alleged members, seizing computers and mobile phones containing terrorist propaganda material as well as pistols, hand grenades and explosives.
The FSB said that criminal cases have been opened against the alleged leader of one the cells and three members, whose online community uses the Tajik language, the state language of the Central Asian ex-Soviet republic of Tajikistan.
It also said the online community has more than 100,000 members spread throughout the former Soviet republics of Central Asia and the Middle East.
The FSB said in February it had detained seven alleged ISIS members in the Sverdlovsk region who were plotting to carry out terror attacks in major Russian cities, including Moscow and Saint Petersburg.
Both ISIS and Al-Qaeda's Syrian affiliate Al-Nusra Front have called for attacks in Russia in response to Moscow's bombing campaign in support of Syrian President Bashar Al-Assad.
ISIS has already claimed a number of attacks on Russian soil, including a deadly shooting at an ancient citadel in Russia's volatile North Caucasus region of Dagestan last year.
Moscow has said part of the reason why it launched a bombing campaign in Syria last year was to prevent ISIS terrorist and other extremists from perpetrating attacks in Russia.
According to FSB figures released in December, nearly 2,900 Russians are fighting or have fought with the terrorist in Iraq and Syria.
