Russian airstrikes have destroyed 74 ground facilities belonging to the Ukrainian military.

This includes 11 airfields, three command centers and a naval base, Russian Ministry of Defense spokesperson Igor Konashenkov said Thursday, Feb. 24.

About 18 radio-locating stations for anti-aircraft missile systems were also destroyed, according to Konashenkov.

However, Konashenkov noted that the strikes are not being carried out against social facilities at Ukrainian military garrisons, such as homes, residential buildings and barracks, in order to avoid casualties among servicemen and their families.

Meanwhile, he said a Russian assault aircraft crashed due to a “pilot error” in eastern Ukraine’s Donbas region.

“The pilot safely ejected and is at his military garrison now,” Konashenkov added.

Pro-Russian separatist militias in Donbas continue a counteroffensive on the Ukrainian Armed Forces with fire support from the Russian army, according to Konashenkov.
