Many children have lost their lives in wars in recent years. Those who survived witnessed extraordinary violence. Many children lost their parents and relatives, and almost all their homes and buildings were destroyed. Children and their families are denied safe access to food, water, electricity, medicine, and hospitals. Hospitals and schools were bombed. Especially children and adolescents are psychologically affected by all these negativities. The degree of impact varies depending on the degree of violence experienced in the war, the age of the children, their upbringing, their financial situation, and whether similar vulnerabilities have been experienced before. Another important issue is that the problems of children and adolescents do not end with the end of the war and emerge as post-traumatic syndrome later in life. One of the impacts of war on children and adolescents is that the violence applied by the authorities becomes legitimized for children. For these reasons, the necessary treatment and psychosocial support should be provided to children and adolescents, as well as to those responsible for the care of children and teachers.
