"During the night on Friday, the body of another Israeli hostage was recovered from the Gaza Strip and repatriated to Israel.
"The retrieval operation, which lasted several hours, commenced at 8:00 p.m. and concluded successfully, with the body being unearthed from an underground location in a compound situated in the southern part of Khan Yunis," a military official informed the Fox News Jerusalem Bureau. "Following the retrieval, the body was transferred to Israel for further identification.
The operation was supported by comprehensive ground and air activities," the official added, highlighting that Hamas and Islamic Jihad are still holding 133 hostages.
The individual was identified as 47-year-old Elad Katzir. While his mother, Hanna, was also held captive, she was released on November 24, 2023, as part of a temporary ceasefire.
A joint statement from the Israel Security Agency (ISA) and the Israeli Defense Forces (IDF) indicated that Katzir had been "murdered in captivity," likely in January of this year. Although Katzir’s sister asserted on Facebook that Hamas had murdered her brother, the ISA and IDF suggested that Islamic Jihad was more likely responsible.
Following an overnight identification procedure conducted by medical officials at the Institute of Forensic Medicine, IDF and ISA representatives informed Elad Katzir's family about the recovery of his body," the statement stated.
"The IDF and ISA offer their deepest condolences to the family. Katzir and his mother were among those abducted on October 7 from Kibbutz Nir Oz.
The ISA and IDF reiterated their commitment to working "in full coordination with the relevant national and security bodies and will continue until the task is complete" to retrieve all hostages.
Katzir, a farmer and social activist, volunteered with the "Hadar Foundation," which advocates for the release of two Israeli soldiers whose bodies are being held in Gaza."
