Ruby Chen holds a poster of his son, Itay Chen, during a protest near Israel's parliament in Jerusalem, Thursday, March 9, 2024. Itay Chen was killed in Hamas' attack on Oct. 7. But unlike scores of other families of soldiers killed that day, the Chens don't have a grave to visit because their son's remains are being held by Hamas in Gaza. The absence of a final resting place is being felt by several dozen families as Israel marks its Memorial Day for fallen soldiers, when cemeteries are brimming with relatives mourning over the graves of their loved ones.
