MOSCOW, May 29. /ITAR-TASS/. About 300 Ukrainian mercenaries who fought in Syria on the opposition side against Bashar Assad returned to Ukraine in March-April and are now participating in the punitive operation of Ukrainian government forces in the southeast of Ukraine, according to a source in the General Staff of the Russian Armed Forces.

After returning from Syria, they joined the battalion of Right Sector radicals participating in the government forces' punitive operation against residents in southeastern regions of the country. Most of the mercenaries are from western regions of Ukraine. Among them are snipers and soldiers of Special Forces known for their cruelty. They fought in more than one "hotspot", including in the North Caucasus where they participated in fighting against federal forces.
