A year later, al-Selek, who lost his leg during the airstrike, still struggles to recover and come to terms with his family's loss in the 50-day Israel-Hamas war. (Photo by Adel Hana/AP Photo)

The probe cleared the military personnel of any wrongdoing, finding no evidence of criminal misconduct. (Photo by Adel Hana/AP Photo)
