All but about 2,000 Russian troops that had been around Mariupol have left and headed north, the Pentagon said Thursday, as intense fighting between Russian and Ukrainian forces continued in the battle for the besieged city’s sprawling steel mill.

Russian airstrikes have bombarded Mariupol, Pentagon spokesperson John Kirby said Thursday, but Putin’s forces have only made incremental progress in the eastern Donbas region where most of the Russian offensive has moved.

Almost 500 additional civilians were also evacuated from the city’s steel plant in the latest humanitarian operation, said Andriy Yermak, head of Ukraine’s presidential office.

The bombardment of the Azovstal steel plant comes amid speculation that Russian President Vladimir Putin wants to tout a major victory in Ukraine on May 9, Russia’s Victory Day. Monday will mark the anniversary of the Soviet Union’s defeat of Nazi Germany in World War II.

Ukrainian President Volodymyr Zelenskyy said the attack was preventing the evacuation of civilians remaining in the plant’s underground bunkers.

“Just imagine this hell! And there are children there,” Zelenskyy said late Thursday in his nightly video address. “More than two months of constant shelling, bombing, constant death.”
