It said on Telegram messaging app that drones were launched from the southern, southeastern and northern directions.
Authorities said the central Ukrainian Cherkasy region was under the attack.
"At night, the enemy massively attacked our Cherkasy region with attack drones. Unfortunately, there were hits on industrial infrastructure in (the city of) Uman," Cherkasy Governor Ihor Taburets said on Telegram.
"As a result, fires broke out in warehouses. In particular, where grain was stored," he said, adding that one person was injured.
The Ukrainian presidential office said in a statement that civilian infrastructure and warehouses were also damaged in the southern Mykolaiv region and eastern Dnipropetrovsk region.
