Children in Gaza and across the border in Israel have lived through three major conflicts in six years. In the summer of 2014, more than 500 children were killed in a 51-day war, all but one of them Palestinian. Almost every child in Gaza lost a loved one. More than a third were left traumatised. On the Israeli border, children lived in constant fear of rocket attacks and underground tunnels. Lyse Doucet follows the lives of children on both sides of the conflict in the midst of the war and through the months that followed, revealing how children born so close are growing further apart with each war.
