The southern Ukrainian city of Zaporizhzhia, which has been serving as a safe haven for thousands of people fleeing the besieged port city of Mariupol, came under fire from Russian forces on Wednesday, Ukrainian officials said.
"Civilian objects have been bombed for the first time in Zaporizhzhia," the regional governor Alexander Starukh wrote on Telegram. "The rockets landed in the area of the Zaporozhye-2 railway station."
He said that there had been no casualties.
Zaporizhzhia is situated some 230 kilometers (143 miles) northwest of Mariupol, which aid agencies say is facing a humanitarian catastrophe amid drastic water, food and power shortages.
Russia denies targeting civilians.
