According to media reports, five members of the Serbian nationalist movement “Chetniks” arrived in the Crimea. Its territory is occupied by Russian troops now. Milutin Malishich and Bratislav Zivkovic, known for their connections with the Russian Cossack organizations, are among the Serbian visitors. In Sevastopol the Serbs took over the watch at a checkpoint at the entrance to the city. Under the pretense of security guard, they stop and inspect passing cars. Chetniks were active participants of the bloody war and ethnic cleansing in the former Yugoslavia. They are irreconcilable to Muslims and Western countries. Increasing the number of the Serbian nationalists in the Crimea may cause a conflict between pro-Russian forces and the Crimean Tatars.
