Ukraine’s security services behind Kirillov's assassination, source tells CNN

 Ukraine’s security services were behind the assassination of Lt. Gen. Igor Kirillov, a source with knowledge of the operation told CNN. 

“Kirillov was a war criminal and an absolutely legitimate target, as he gave orders to use banned chemical substances against the Ukrainian military,” the source told CNN. “Such an inglorious end awaits all those who kill Ukrainians. Retribution for war crimes is inevitable.”
