Ukrainian officials reported missile and artillery attacks by Russian forces overnight Thursday on several towns and cities in the south, including Mykolaiv and Kryvih Rih.
The regional administration in Mykolaiv said the river port was attacked again with S-300 missiles. Three missiles hit the Petro Mohyla Black Sea university, causing extensive damage.
South of the city, the town of Halytsynove was struck by Russian rockets Thursday, destroying several residential buildings and injuring three people.
In neighboring Dnipropetrovsk, the head of the regional administration, Valentyn Reznichenko, said there was a night of "massive enemy attacks" with the cities of Nikopol and Kryvih Rih hit.
One man was killed in a village near Kryvih Rih, he said. And a 12-year boy was injured when Russian missiles hit his home near Synelnykove, which is about 100 kilometers (62 miles) from the front lines.
Nikopol -- which is on the opposite side of the Dnipro River to the Zaporizhzhia nuclear plant -- was hit by 10 artillery shells, according to Reznichenko. Power had been disrupted and there was extensive damage, he said.
