On Friday, Russian Defense Ministry Spokesman Igor Konashenkov announced that planes of the Russian Aerospace Forces destroyed 54 military facilities in Ukraine in the past 24 hours, while the Russian air defenses have brought down a Ukrainian Unmanned Aerial Vehicle (UAV).

"Tactical, army and unmanned aircraft hit 54 military facilities of Ukraine. Among them are three command points, four multiple rocket launch systems, four ammunition depots and 44 sites where military hardware was concentrated," he added.

In the last 24 hours, according to Konashenkov, a Ukrainian UAV was hit in midair. 

On February 24, the Russian military launched an operation against Ukraine for demilitarization and denazification purposes. 

Today, Ukrainian troops shelled a hospital in Donetsk, injuring two medical workers and one civilian, the Donetsk People's Republic (DPR) Territorial Defense Headquarters said on Friday.

"As a result of the shelling by the Ukrainian forces in the Petrovskyi district of Donetsk, the building of hospital No. 14 was damaged, three people were injured: two employees of the medical facility and one civilian," the defense headquarters wrote on Telegram.

The spokesperson for the People's Defense Units of the DPR, Eduard Basurin, confirmed Friday that Russia has established a no-fly zone over Donbass to protect its airspace from attacks.

In an interview with Rossiya 24 TV, Basurin said in response to a question about closing the airspace over Donbass and creating a no-fly zone over it, "Yes I think so".

On the DPR head's request for strengthening the air defense systems in the Donbass, he said that the Republic "does not need to transfer similar systems, because Russia's control of the skies over Donbass is considered sufficient by itself."
