Russia has attacked port infrastructure in Ukraine's southern Odesa region with drones in overnight strikes that also ​damaged residential buildings and a hospital and left ‌two people wounded, Ukrainian officials said on Wednesday.

Regional Governor Oleh Kiper, writing on Telegram, said the attack in the south of the ​Odesa region destroyed the admissions department of a ​hospital there, and badly damaged other parts of ⁠the facility.

At the time of the attack, medical staff ​and patients were in a shelter, and they were later ​moved to another facility, he said.

Regional prosecutors said port infrastructure facilities came under attack, without giving details.

Emergency services said two people were ​hurt in fires in a residential area. They posted ​pictures of buildings engulfed by fire and firefighters battling the blazes.

Kiper ‌added ⁠that a fire was also recorded at the Danube Biosphere Reserve, a nature reserve in the region.

The Odesa region, which houses major Ukrainian seaports and river ports on the ​Danube, has ​been a ⁠repeated target of Russian attacks during Moscow's more than four-year-old war.

Ukraine's air force said Russia had ​launched 171 drones at the country since ​Monday ⁠evening. The air defence units downed or neutralised 154 drones, it added.

One person was killed and two others wounded in ⁠a ​separate drone and missile attack in ​the northeastern Sumy region, which caused large-scale fires in a residential area, ​local officials said.
