“...none?”
Serhiy Kokurin.
Natural result of Ukrainians force fed 75 years of “Slavic brotherhood” crap, which no one buys anymore.
You forgot to mention Ruslan Cossackov, of the Crimean self-defense forces (ostensibly the “enemy” of the Ukrainians). Both he and Serhiy Kokurin were killed by the same third party sniper (widely believed to be a provocateur). The funerals of both Kokurin and Cossackov were held together as a display of brotherhood.
