(NewsNation) — The father of Israeli soldier Itay Chen walked out of Benjamin Netanyahu’s Friday address to the United Nations because of what he considers a glaring omission: The Israeli prime minister named the 20 living hostages still being held in Gaza but did not mention another 28, including Chen, whose bodies are with Hamas.

“There are 48 hostages,” Ruby Chen told “Elizabeth Vargas Reports” later in the day. “My son is no less of a hostage.”

His 19-year-old son, Itay, a dual U.S.-Israeli citizen who served in the Israel Defense Forces, is believed to have been abducted and killed during Hamas’ Oct. 7, 2023, incursion into Israel. Terrorists took both living and dead hostages during the attack, which left nearly 1,200 people, mostly Israelis, dead and sparked the war in Gaza.

Netanyahu appeared at the U.N. General Assembly and defended his government’s continuing efforts to stamp out Hamas as other countries criticize Israel for the deaths and suffering of Palestinian civilians. Some countries have recognized a Palestinian state. On Friday, several U.N. delegates walked out as the prime minister was introduced.

Ruby Chen continuously wears a yellow piece of tape that tallies the number of days since the Oct. 7 attacks — and the number of days that his family has not had some sense of closure. The elder Chen said he’s tired of Israeli officials saying they need just a little more time to “finish the job” before a ceasefire deal can be struck with Hamas.

“That is the problem with the prime minister. He always believes that tomorrow there’s a better deal than the one in front of him today, and that messes things up,” Chen said.

He said he hopes President Trump can persuade Netanyahu when the two meet Monday.
