Their son Itay, a soldier who was killed in Hamas' Oct. 7 attack, is among the more than 30 Israelis whose remains are believed to be in Gaza. The procession came ahead of Israel's Memorial Day, when cemeteries will be brimming with relatives mourning over the graves of their loved ones. (AP Photo/Ohad Zwigenberg)
