(NEW YORK) -- Ukraine's military has ended its combat mission in the city of Mariupol and hundreds of Ukrainian fighters are being taken by bus to Russian-controlled territory after nearly three months of heavy fighting in the port city. Russia began its attacks on the city in early March.
The Ukrainians and Russians struck a deal to exchange badly injured soldiers from the Azovstal steel plant in Mariupol for Russian prisoners of war, Ukraine's Deputy Defense Minister Anna Malyar told a Ukrainian TV station.
Mariupol's mayor confirmed that a cease-fire remains in place in the port city.
The Ukrainian military ordered remaining troops who had been sheltering beneath the Azovstal steel factory to focus on efforts to save the lives of their personnel.
More than 260 Ukrainian soldiers were evacuated through a humanitarian corridor, some of whom were injured, according to Ukraine's defense minister.
Malyar said that 53 wounded soldiers are being transported from Azovstal to Novoazovsk where they will receive immediate medical attention.
"About Azovstal, we hope that we'll manage to save their lives. There are seriously injured among them. I want to stress that we need our defenders alive. The operation to rescue them was launched by our military. We work on getting them home and this work demands delicacy and time," Ukrainian President Volodymyr Zelenskyy said in his daily address.
Another 211 Ukrainian fighters were accompanied by Russian forces from Azovstal to Olenivka in rebel-held Donetsk, where they will be part of the exchange for Russian prisoners of war.
"As a part of an exchange deal, 50 wounded were evacuated from Azovstal to Novoazovsk. Negotiations are underway for them to be transferred to Zaporozhzhya," another source told ABC News, confirming the exchange.
Russia's state-run TASS reported that Russia's defense ministry confirmed an agreement was reached on Monday to evacuate wounded Ukrainian troops from the plant and transport them to a medical facility in Novoazovsk to "provide them with all the necessary assistance."
The Russian defense ministry on Tuesday said 265 Ukrainian militants have laid down arms and surrendered, including 51 who are seriously wounded. All those in need of medical assistance were sent for treatment to a hospital in Novoazovsk, Donetsk People's Republic.
