Around 300 Ukrainian military contractors that fought for Syrian opposition against president Bashar Asaad in March-April came back to Ukraine and are taking part in military punitive operation against southeastern region of what used to be Ukraine.
Upon arrival mercenaries have joined radical battalions of Right Sector that are taking part in punitive operation.
Same source reports that most of the mercenaries are natives of western Ukraine.
Editor’s note: Radical elements from western Ukraine in the past have fought in other Muslim countries. Many are friendly with various terrorist organizations. For example Sashko Biliy and his men joined terrorists in Chechnya. They have personally tortured and killed local soldiers and government officials there.
