Flawed migration laws allow emissaries of international extremist organizations to get into Russia, Federal Security Service Director, head of the National Counter-Terrorism Committee (NCC) Alexander Bortnikov said.
"Imperfection of current migration laws creates conditions for illegal migration, which enables bearers of radical religious views to come here from abroad," he said at a NCC meeting.
These are emissaries of international extremist organizations and missionaries of various kinds, he said.
"We expose and stop operations of this category of foreign citizens in the majority of constituents of the [Russian] Federation," Bortnikov said.
This factor and online spreading of the extremist ideology have brought about "metastasis of religious extremism not only in a number of republics of the North Caucasus where militants continue to operate but also in certain territories of the Northwestern, Volga, Siberian and Urals Federal Districts where followers of radical religious ideas create clandestine groups," he said.
