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.

Two explosions were heard coming from the eastern areas of Deir al Balah in the middle of the Gaza Strip in the past hour. ABC News does not know the source of these explosions at this time.

There has been no official word from either party -- Israel or Hamas -- on any action on the ground in Gaza.

Israeli Prime Minister Benjamin Netanyahu announced that strikes would resume on Gaza earlier on Tuesday.

Israel decided to carry out strikes in Gaza because of an attack on Israel Defense Forces troops in the IDF-controlled area of Gaza, east of the yellow line, on Tuesday, and for "violating the agreement," to return the remains of all the dead hostages still being held in Gaza, Israeli Defense Minister Israel Katz said in a statement Tuesday.

"The attack on IDF soldiers in Gaza today by the Hamas terrorist organization is crossing a bright red line to which the IDF will respond with great force," Katz said in the statement, originally in Hebrew.

"Hamas will pay with compound interest for attacking the soldiers and violating the agreement to return the fallen hostages," he added.

As a part of the ceasefire deal, the IDF withdrew to an established yellow line in Gaza. IDF troops control parts of Gaza east of the yellow line -- at these borders, the IDF still controls more than 50% of Gaza.

Hamas attacked IDF troops in this area of Gaza on Tuesday, violating of the ceasefire agreement, two Israeli officials told ABC News.

Israeli authorities were also particularly aggravated after the remains returned by Hamas via the Red Cross on Monday night were identified as a hostage whose remains had previously been found in Gaza by IDF troops, one Israeli military official said.

The military official said one of the IDF’s surveillance cameras captured footage they say shows Hamas staging the discovery of a body in Gaza in front of the Red Cross on Monday.
