"Semen is gone... Near the Donetsk airport. No details are yet available. He was the commander of the group unofficially called Seminariia. A master of sports of wrestling. Until last summer, we had been within one Right Sector unit. I never fought alongside Semen though - they always acted as a separate group," the message notes.
According to Bilozerska, Seminariia fighters got the glory of desperate men at the front.
"They stayed near the Donetsk airport even under the most pressing circumstances - either because of an enemy attack or the acts of prosecution against volunteers. Semen's death is a serious loss for the Ukrainian volunteer movement..," the journalist wrote.
