A Russian bomb hit a hospital in northeastern Ukraine on Wednesday, shattering windows, destroying equipment and prompting the evacuation of dozens of patients, officials said.

Volodymyr Tymosko, Kharkiv police chief, said a bomb hit the hospital at 9:45 p.m. in the town of Veliki Burluk, northeast of the Kharkiv regional capital of the same name, while a second one fell nearby.

Via Facebook, he added that 38 people, the 33 patients, 2 of whom are bedridden, were hurriedly removed from the structure.

Regional governor Oleh Sinekhubov said via Telegram that cleaning work was being carried out at the hospital at night and added that four people with minor injuries were treated on the spot.

According to Mr. Sinekhubov, the fact that the hospital staff reacted immediately when the alarm was called allowed the emergency evacuation to go smoothly. Patients were referred to other health facilities or outpatient clinics.

Photos uploaded to social media by Ukraine’s emergency services showed nearly all of the hospital’s windows broken and debris on the street in front of the building.

Hospital rooms are still shown with damaged equipment and debris strewn inside.

Attacks by the Russian army in Kharkiv have been frequent in recent weeks.

Russia’s Defense Ministry did not immediately respond to a Reuters request for comment.

Russia denies targeting political infrastructure, although medical and educational facilities have been bombed during the 24-month-old war.

Kharkiv Mayor Ihor Terekhov reported via Telegram that Russian drones hit infrastructure in the city. He did not say if there were any casualties.
