Fourteen-year-old Serhii Sorokopud is still haunted by what happened when Russian tanks rolled into his village five months ago. He lifts his T-shirt to show the deep scars across his back -- a reminder of a trauma both hidden and visible.
Russian troops set up a military camp in the small farming community of Yahidne, northeast of the capital Kyiv, on March 3, on their advance toward the capital. Serhii and his family were taken captive with hundreds of others in the basement of his school. Ten days later, as he stood in line for food in the playground, there was an explosion and he was struck by shrapnel.
"First, there was a strong blow to the back. I fell, couldn't get up, couldn't move," he told CNN on Thursday, showing the spot behind his school where he was hit. "People ran over and lifted me up. I couldn't even walk. There was a lot of blood."
