Omer Neutra, who grew up on Long Island, is one of two deceased American Israeli hostages who remains held by Hamas, and his parents are desperate for his body to be returned.

“Omer does not deserve to end up under the rubble in Gaza. He needs to be brought home, and he needs to be buried with dignity,” his mother, Orna Neutra, told ABC News.

Orna Netura described the past week as “insane,” saying every night she and her husband have been given the news that a small number of deceased hostages will be returned. Only hours later, normally in the middle of the night, the couple gets a call to say it’s not their son.

Asked what it would mean to her to give her son a proper burial, she said she’s been imagining the moment that he’s brought back.

“I know I’m going to be devastated, but I also know it’s really necessary,” she said.

Omer Neutra was a captain in the Israel Defense Forces on Oct. 7 and his parents learned of his death more than one year later. Omer’s dad, Ronen Neutra, described him as a “fun loving kid” and a “born leader,” and said people “gravitated to him.”

The Red Cross is on its way to a meeting point in southern Gaza to receive a coffin of a deceased Israeli and transfer it to the Israel Defense Forces, the IDF and the Israeli Security Agency said in a joint statement.

President Donald Trump on Monday threatened to "eradicate" Hamas if the militant group breaks the ceasefire agreement.

"We have a little situation, relatively, with Hamas, and that will be taken care of very quickly if they don't straighten it out themselves, because they're in violation of their agreement," Trump said as he took reporter questions at a White House event with Australia's prime minister.

"We made a deal with Hamas that, you know, they're going to be very good, they're going to behave, they're going to be nice and if they're not, we're going to go in, we're going to eradicate them if we have to," Trump added. "They'll be eradicated, they know that."

Trump was then asked if such a scenario would involve U.S. military on the ground.

"No, it won't be on the ground at all because we don't need to because we have many countries, as you know, signed onto this deal," Trump said. He claimed other countries would want to go in and combat Hamas, and that Israel would do it "in two minutes if I told them"

"But right now we haven't said that. We're going to give it a little chance and hopefully there will be a little less violence," Trump said.

President Donald Trump on Monday was asked what his administration is doing to ensure the fragile ceasefire between Israel and Hamas holds after a weekend of violence in Gaza.

"A lot of steps," Trump responded as he took questions from reporters during a bilateral meeting with Australian Prime Minister Anthony Albanese, though he didn't elaborate on what those steps were. "And right now, it's in the hands of others."

White House special envoy to the Middle East Steve Witkoff and Jared Kushner arrived in Israel on Monday to bolster the shaky agreement and try to continue implementation of the second phase of Trump's 20-point peace plan.

Israel handed over bodies of 30 other Palestinian prisoners to the Gaza Strip on Wednesday as a part of the ceasefire agreement, according to the Nasser Medical Complex in Khan Younis.

Israel has now returned 165 Palestinian bodies, according to the enclave's government media office.

Not all of the Palestinian bodies returned by Israel could be identified by their families "due to the severe circumstances" surrounding their deaths, according to the Palestinian Civil Defense report on Wednesday.

A collective funeral ceremony was held for 54 unidentified Palestinians on Wednesday in Deir al-Balah, in central Gaza, as the Civil Defense reported.

Signs of abuse, beating, handcuffing, and blindfolding, and hanging on the neck were seen on the returned bodies, according to the Gaza Media Office and the Gaza Ministry of Health.

Rejecting reports of any torture signs, the Israeli military told ABC News in a statement on Wednesday that "the IDF did not tie any bodies prior to their release to the Strip," adding that they operate "strictly in accordance with international law."

Moureen Kaki, an American-Palestinian aid worker who examined living Palestinian prisoners and detainees upon their return to the Gaza Strip after the peace deal, told ABC News last week that all of 35 prisoners who talked to her had "experienced torture,” while in Israeli custody.

Some said they were beaten by Israeli soldiers “as early as two hours before their arrival into Gaza when they were waiting on the bus,” Kaki said. She added that three Palestinian men had open gunshot wounds from the last three weeks at the time.
