The FSB press service stated that the cell was controlled by foreign emissaries, adding that citizens of Russia, Central Asia, and Caucasian republics were involved in the activities of the cell.
Meanwhile, the Russian Investigative Committee added that the apprehended Daesh members had been recruiting new adherents and calling for attacks on police personnel.
"Seven people suspected of organizing [the cell] and participating in the activities of the terrorist organization were detained… The participants carried out propaganda work to involve new supporters in the organization's activities, including calling for attacks on law enforcement officers," the committee said.
The press service of the Russian Federal Security Service (FSB) said that firearms, ammunition, means of communication, electronic data storage devices and extremist literature had been seized from the members of the IS cell.
Last week, Russia's Federal Security Service announced they have detained five members of a Daesh cell, as well as jihadists in several regions of the country.
It said the detainees had been planning to carry out a series of attacks on businessmen and then "go to the Syrian Arab Republic to participate in hostilities".
