"Two of them — Serhiy Suprun and his comrade Biker — evacuated more than twenty injured cyborgs [Ukrainian soldiers who fought at the airport] from the Donetsk airport," Oleksandr Danylyuk wrote on his Facebook page.
The civil activist noted that the volunteers might have witnessed the Right Sector's lawless actions. Now the group is intimidating the doctors into keeping quiet about what they had seen.
"You can form volunteer armies. But there will be no volunteer prisons in Ukraine," Danylyuk wrote.
The Right Sector is an alliance of Ukrainian nationalistic organizations. The Right Sector has participated in the Donbass conflict with its so-called volunteer formations. The group's activists were involved in the Odessa massacre on May 2, 2014, when 48 people were killed by nationalistic forces.
