The Ukrainian Security Service has prevented the attempted transit of followers from the ISIL terrorist organization (banned in Russia) from Syria to Western Europe via Ukraine's Kharkiv.

The illegal transit was organized by a citizen from a neighboring country, who had been illegally staying in Ukraine, and was suspected of possible engagement in terrorist activity, the Ukrainian Security Service press center said on Wednesday.

The man was hosting ISIL followers in an apartment in a residential area of Kharkiv, under religious disguise, and planned to transport them to Europe.

The security service detained the illegal transit organizer and another two people, who were about to take the illegal trip.

The police are conducting urgent operative and investigative procedures.
