April 29 (Reuters) - 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.
