MOSCOW, January 27. /TASS/. Russia's Federal Security Service (FSB) has exposed a clandestine cell of the Hizb-ut Tahrir terrorist organization, outlawed in Russia, in the Kaluga region, the FSB said in a statement on Wednesday.

"Federal Security Service and National Guard officers have exposed a clandestine cell of the Hizb-ut Tahrir international terrorist organization (outlawed by the Russian Supreme Court in 2003) in the Kaluga region," the statement reads.

According to the FSB, the cell's members carried out activities violating the Russian Constitution, based on the idea to create the so-called global Caliphate, destroy secular public institutions and overthrow the current government by force.

"They spread terrorist ideas among the region’s residents at secret meetings and recruited local Muslims to their ranks," the FSB added.

A large amount of banned Hizb ut-Tahrir propaganda materials, communication equipment and digital storage devices were seized from the homes of the detained suspects. A criminal investigation has been launched.
