KYIV—Ukraine on Wednesday carried out its biggest exchange of prisoners of war since Russia invaded, securing the release of 144 of its soldiers, including 95 who defended Mariupol’s steelworkers, Ukraine’s military intelligence agency said.
The majority of the Ukrainians were badly wounded, suffering from gunshot and shrapnel wounds, blast traumas, burns, fractured bones, and amputated limbs, the agency known by the acronym GUR said in a statement on Telegram.
