Ukraine evacuated its remaining combatants from besieged Mariupol on Monday, ending its last stand to prevent Russia from capturing the strategic port city after weeks of heavy Russian bombardment.
Hundreds of Mariupol residents also sought shelter in the complex. In early May, the first civilians evacuated the shattered steelworks and were escorted to safety by the United Nations after weeks of negotiations with Russian and Ukrainian forces.
In late April, Russia declared victory over Mariupol, even as the contingent of Ukrainian troops held out at the plant and refused Moscow’s demand to lay down their arms. Russian forces now control the city, a strategic seaside hub with a prewar population of roughly 450,000.
Officials in Ukraine say that as many as 20,000 civilians in Mariupol may have been killed during the Russian siege.
