As Israel has announced steps to increase humanitarian aid in Gaza, a former Israeli-Argentinian hostage knows first-hand what that could mean for captives of the Hamas militant group. Iair Horn, who spent a year and a half in captivity, said hostages could tell when more aid was available because they would receive more food. Hamas militants kidnapped Horn from his home at Kibbutz Nir Oz, along with 250 other people, during the group's cross-border attack on Oct. 7, 2023.
