A YOUNG BOY — wearing a camouflage jacket, a Ukrainian flag wrapped around his neck like a scarf, and a smile — flashes the victory sign on the central square of Kherson during the celebration of the city’s liberation by the Ukrainian army. The words “No War” crawled in silver on the wall inside of a bombed-out apartment building in Kharkiv. A couple, both members of the Kyiv Territorial Defense and just married under martial law in Kyiv, and sit outdoors, cuddling, the bride holding a bouquet of white roses, the groom, a rifle. These are just a few of the powerful images in Fighting: Ukrainian War Photographers, an exhibit of photos taken by 16 Ukrainian artists and photographers currently serving on the frontlines of the Russian invasion of their country. Fighting opens Oct. 5 at Silver Street Studios at Sawyer Yards.
