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 Donetsk People's Republic, Eduard Basurin, confirmed today, 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."

Russia had launched a special military operation for several reasons, such as NATO's eastward expansion, the Ukrainian shelling of Donbass, and the aggression of Ukrainian forces against the Donetsk People's Republic and Lugansk People's Republic, which has been ongoing since 2014, as well as denazifying and demilitarizing Ukraine.

The Russian Defense Ministry confirmed that the special operation is targeting Ukrainian military infrastructure only and the civilian population is not in danger.
