Hamas has handed over the body of Israeli hostage Shiri Bibas, Hamas-run Al-Aqsa television said Friday, citing the group's senior official Mahmoud Mardwai.

Earlier, Hamas rejected Friday Israeli Prime Minister Benjamin Netanyahu's "threats" to make the Palestinian group pay after he accused it of violating the ceasefire by not returning the hostage Bibas.

"We reject the threats issued by Benjamin Netanyahu as part of his attempts to improve his image," Hamas said in a statement and called on Israeli authorities to return the body of a Gazan woman that the group had handed over on Thursday, claiming it was that of Bibas.

The movement affirmed its "seriousness and full commitment" to its responsibilities under the ceasefire, and said it had "no interest in failing to comply or holding on to any bodies." However, it admitted "the possibility of an error or mix-up of bodies," which it attributed to Israeli bombing of the area where the Bibas family was located along with other Palestinians.

Hamas said it would inform mediators of the results of its "investigation and examination" into the circumstances of the body's return.

"It is likely that Mrs Bibas' body was mistakenly mixed with others found under the rubble," an official said, adding that the group was "investigating" the issue.

This came after Israel stated that one of the bodies handed over by Hamas on Thursday was not that of Bibas, as the group had claimed.

Hamas handed over bodies it said were of four hostages, including three members of the Bibas family — Shiri Bibas and her two young sons — along with an elderly captive.

While the identities of the Bibas boys — Kfir and Ariel — and the elderly hostage, Oded Lifshitz, were confirmed by Israeli forensic experts, the fourth body was not that of Shiri Bibas, according to Israeli officials.

Israel has so far not confirmed the death of Shiri Bibas.

The Hamas official said that the group had informed the mediators in November 2023 that it was ready to hand over the bodies of the three Bibas family members.

"Mediators were informed at the time and it was also announced in a statement when the Bibas family was killed along with their captors in an Israeli air strike," the official said.
