“Unfortunately, yes, there is heavy fighting in Azovstal today,” Vadym Boichenko told Ukrainian television.
He said city officials had “lost contact” with Ukrainian forces inside the plant and had no way of knowing “what’s going on, whether they are safe or not.”
The Ukrainian military said Tuesday that Russian forces had launched an offensive to rout troops inside Azovstal shortly after the United Nations and Red Cross confirmed that more than 100 civilians had been evacuated from the plant.
Russia confirmed it was attacking Ukrainian positions at the plant with “artillery and aircraft” but earlier Wednesday the Kremlin denied Russia was storming Azovstal.
Boichenko said Russia was attacking with heavy artillery, tanks, and warplanes, adding that warships next to coastal steelworks were also involved in the attack.
“There are local residents there, civilians, hundreds of them there. There are children waiting for rescue. There are more than 30 kids,” the mayor added.
Mariupol is among the most badly hit cities by Russia’s invasion of Ukraine.
