NBC News is not naming the boy and his relatives because they fear for their safety.
Among the entries the boy drew pictures of tanks, burning buildings and helicopter gunships.
“You realize that he understood everything that happened and saw everything,” Sosnovsky said. “It’s terrible. When I read the diaries for the first time … it was almost impossible. Very heartbreaking.”
Along with the depictions of war are more innocent pictures. The boy drew an imagined celebration for his coming birthday, complete with a cake and friends in party hats.
“I woke up and smiled yesterday,” he wrote. “My grandma went for water and returned. By the way, my birthday is soon.”
But the reality of childhood in a city under siege broke through.
“My two dogs were killed, and my grandma Halya,” he wrote. “And my favorite city, Mariupol, has died.”
