People attend a rally for the release of the hostages kidnapped by Hamas at Dag Hammarskjold Plaza near the U.N. headquarters on Jan. 12 in New York City.
As the Israel-Hamas war nears its 100-day mark, well over 100 hostages of the conflict are still estimated to be held in Gaza, with advocates and global groups drawing attention to their plight and calling for their immediate release.
