The doors of bomb shelters are open in a public park in Sderot, Israel, Wednesday, July 28, 2021. No place in Israel has been hit harder by Palestinian rocket fire than Sderot, a working-class town just about a mile (1.5 kilometers) from the Gaza border. Although Sderot is enjoying an economic boom and revival, a generation of children and parents are suffering from the traumatic effects of two decades of rocket fire that experts are still struggling to understand.
