VELIKIY NOVGOROD, February 3 /TASS/. Russian security services have discovered terrorists who penetrated into Russia’s Novgorod region under the guise of migrants, Vladimir Bulavin, the Russian president’s envoy in the North-Western Federal District, told journalists on Wednesday.

"Law enforcers in the Novgorod region have exposed migration flows, which include representatives of terrorist organizations Hizb ut-Tahrir and Al Islami as well as other terrorist groups banned in Russia," Bulavin said.

The press service of the regional Federal Security Service (FSB) department failed to react quickly to the envoy’s words.
