An “industrial facility” in the southern port city of Mykolaiv was hit in the overnight attack according to local governor Vitaliy Kim.
A fire had subsequently broken out before being extinguished, he said on Telegram, adding there were no casualties.
Mykolaiv is located on the Black Sea, about 170 kilometres (100 miles) from Moscow-annexed Crimea.
Russian forces have frequently targeted it since the start of Moscow’s invasion in February 2022.
Sergiy Bratchuk, spokesman for the Odesa military region, had previously reported air defences had been activated in the area.
Russia was “attacking the south of Ukraine with attack drones,” head of the Odesa region’s military administration, Oleg Kiper, said on Telegram.
He warned residents to stay in shelters.
Air alerts were also announced in Mykolayiv, Kherson, Zaporizhzhia, Donetsk, Kharkiv, Dnipropetrovsk, Poltava, Kirovograd, and Cherkasy.
Russia’s invasion last year saw Ukraine’s Black Sea ports blocked by warships until the agreement, signed in July 2022, allowed for the passage of critical grain exports.
The deal expired at midnight in Istanbul (2100 GMT) after Russia refused an extension, arguing that the parts of the deal allowing the export of Russian food and fertilisers had not been honoured.
