MOSCOW, June 24. /ITAR-TASS/. More than half-a-million Ukrainian citizens fleeing besieged towns find shelter across the border in Russia’s southern Rostov region, say latest figures from the Federal Migration Service (FMS) released on Tuesday.

Ukrainian refugees are focused mainly in the Rostov, Belgorod, Voronezh and Kursk regions, as well as in Russia's far eastern Chukotka, FMS chief Konstantin Romodanovsky told an assembly of the Russia-European Union Dialogue on Migration.

“The Belgorod, Rostov, Voronezh and Kursk regions are the boundary regions, where Russia faces a lot of problems today because of Ukrainian citizens fleeing the country amid the crisis in Ukraine,” Romodanovsky said.

From 9,000 to 13,000 Ukrainian citizens have crossed into Russia through border entry points this month, latest figures say. Rostov region now accommodates 510,000 refugees, says the migration service.

The Russia-EU Dialogue on Migration was launched in 2009, when Russia proposed setting up a modern, flexible and non-bureaucratized structure. Its concept is comprehensive study of the global phenomenon of migration, firstly between Russia and countries of the European Union.
