The body of American Israeli hostage Omer Neutra has been returned to Israel, Israeli officials said, as they identified each of the three sets of remains released by Hamas overnight.

All three were soldiers killed in the Oct. 7, 2023, attacks, whose bodies were taken into Gaza, according to the Israel Defense Forces.

The remains of Neutra, a captain, were returned along with those of Col. Assaf Hamami and Staff Sgt. Oz Daniel, the IDF said in a statement.

Israel said that it received three bodies from Gaza via the Red Cross on Sunday.

The remains will transferred to the Ministry of Health's National Center for Forensic Medicine to confirm their identities, according to a statement Sunday from the Israeli prime minister's office, after which the families will be informed.

Prior to this transfer, there were 11 remaining hostage bodies in Gaza, including two Americans.

A further 30 bodies were transferred from Israeli authorities to authorities in Gaza via the International Committee of the Red Cross, the organization said in a statement on Friday.

This return of bodies is part of the ongoing ceasefire agreement between Israel and Hamas.

Including this transfer, Israel has returned 225 bodies to Gaza since the ceasefire began on Oct. 10, the Hamas-run Gaza Ministry of Health said.

"Local health and forensic authorities are responsible for taking all possible measures to identify the remains of those deceased. Local health authorities in Gaza have confirmed the number of deceased received today is 30," the ICRC said.

The International Committee of the Red Cross called Hamas' alleged staging of the discovery of a body in Gaza while Red Cross observers were in attendance on Monday "unacceptable."

The Israel Defense Forces released a video that it said shows Hamas staging the discovery of a hostage body in Gaza.

"It is unacceptable that a fake recovery was staged, when so much depends on this agreement being upheld and when so many families are still anxiously awaiting news of their loved ones," the ICRC said in the statement on Tuesday.

ICRC observers accompanied Hamas earlier this week to provide any needed technical guidance in recovery efforts, but the ICRC does not participate in searching for the deceased or in physical recovery of remains per international law.

"The ICRC is raising its concerns directly with the parties," the organization added.

Israeli authorities cited this as one of the reasons for conducting strikes in Gaza on Tuesday, threatening the fragile ceasefire in place.
