Ukraine has lost an F-16 aircraft and its pilot while repelling a Russian missile and drone strike, according to country’s air force, as heavy fighting in the war, now in its fourth year, grinds on daily with no signs of a ceasefire on the horizon, Aljazeera reported.

After shooting down seven air targets, the plane was damaged and lost altitude overnight, the Ukrainian military said in a statement published on Telegram on Sunday.

“This night, while repelling a massive enemy air attack, a pilot of the 1st class, Lieutenant Colonel Maksym Ustimenko, born in 1993, died on an F-16 aircraft,” it said, according to Aljazeera.
