Kateryna survived in Mariupol for two months. Her house had a deep, albeit cold, basement. It was -11 outside and -3 degrees indoors, she says. The worst thing was when Kateryna learned that her son's house had been hit by a plane shelling. When she ran there under fire, she saw holes in the wall of the apartment from the street. But neighbors reassured her that her son's family had survived and had already left the city. The woman herself stayed in the burned-out Mariupol until the end of April, when her son managed to rescue his mother and sister with the help of volunteers.
