Katzir, 47, had been abducted from Kibbutz Nir Oz on October 7. His mother, Hana Katzir, 77, also taken hostage by Hamas, was released in November, while his father Avraham-Rami was murdered in his home on October 7.
The Palestinian Islamic Jihad terror group published a video of Katzir in January speaking from captivity and pleading for the Israeli government to stop the war and to bring all the hostages home.
Israeli media and the IDF estimate that he was murdered by his captors the same month the video was published, in January.
Katzir’s sister, Carmit Palty Katzir, blamed Israeli authorities for her brother’s death in a Facebook post. She accused Israel’s leadership of being “cowardly and driven by political consideration,” arguing that had a truce deal been reached her brother would have returned alive.
