Many badly wounded fighters are among the 1,000 Ukrainian troops still holed up at the sprawling Azovstal steel plant, the last major holdout in the port city of Mariupol, Deputy Prime Minister Iryna Vereshchuk said Tuesday.

About 100 civilians also remain trapped in the maze of bunkers and tunnels, she said.

“Hundreds are injured,” Vereshchuk told AFP. “There are people with serious injuries who require urgent evacuation. The situation is deteriorating every day.”

Pavlo Kyrylenko, head of the Donetsk Regional Military Administration, said Russian bombardments have targeted the complex dozens of times in the last day or so.

“It is easier to say when the shelling does not happen than when it happens,” he said. “Aviation and artillery are almost constantly at work there.”

Russian troops have overwhelmed most of the embattled city, home to 450,000 people before the war. Local officials say fewer than 100,000 remain, but Russia has struggled to complete a takeover that would deprive Ukraine of an important port while providing Russia with a land corridor to the Crimean peninsula and a staging area to send troops elsewhere in the country.
