The bodies of the three hostages, Corporal Nik Beizer, Sergeant Ron Sherman and French-Israeli Elia Toledano, were brought back to Israel in December following their deaths the previous month.

"The findings of the investigation suggest a high probability that the three were killed as a result of a byproduct of an IDF air strike, during the elimination of the Hamas Northern Brigade commander, Ahmed Ghandour, on November 10th, 2023," the military said in a statement, referring to the three captives.

"This assessment is based on the location of where their bodies were found in relation to the strike's impact, performance analysis of the strike, intelligence findings, the results of the pathological reports, and the conclusions of the Forensic Medicine Institute."

"This is a high-probability assessment based on all of the available information, but it is not possible to definitively determine the circumstances of their deaths," the military said.

The bodies of the three hostages were recovered on December 14.

The military said its investigation revealed that the three captives had been held in a tunnel complex from which Ghandour operated.

"At the time of the strike, the IDF did not have information about the presence of hostages in the targeted compound," the military said.

"Furthermore, there was information suggesting that they were located elsewhere, and thus the area was not designated as one with suspected presence of hostages."
