"We lost the legendary commander of Luhansk-1 battalion. Serhiy Hubanov was one of these Luhansk-based policemen who did not abandon their loyalty oath to Ukraine. He dreamed of watching the yellow-blue banner unfurl over Luhansk. The day will come, and this dream will come true. Eternal gory to our hero!", Zelensky commented.
