Oleg Khotin, the head of Interior Ministry's forces in Chechnya, said the militants are divided into approximately 75 small groups. He said around 40 of the militants are believed to be foreigners.
Khotin added that the militants are concentrated in Chechnya's south, but acknowledged they retain a significant presence in the regional capital, Grozny.
Russia has been fighting separatists in Chechnya since the mid-1990s.
