Ilana Gritzewsky, who was released from Hamas captivity in Gaza, is campaigning for the release of other hostages still being held by Hamas. Gritzewsky's partner, Matan Zangauker, is among the hostages that Hamas continues to hold more than 500 days later. Gritzewsky has devoted herself to advocating for the release of the remaining hostages, including her partner and two men she last saw in a Hamas tunnel. The fate of the hostages has become more precarious as Israel has returned to fighting in Gaza to pressure Hamas into releasing more captives.
