U.S. officials say it’s not yet known if any Americans will be among the 50 hostages released by Hamas following a deal reached Wednesday.

Qatar announced that Hamas will free 50 women and children, while Israel has agreed to release 150 Palestinian women and teenagers being held in its detention centers. The two sides also agreed to a four-day pause in their war, which could be extended if Hamas releases additional hostages.

Two American women and an American child who is about to turn 4 years old are among the 240 hostages being held in the Gaza Strip, John Kirby, White House National Security Council spokesman, told Spectrum News on Wednesday.

“It’s our fervent hope that those three Americans will be released as a part of this deal, but we're going to have to watch and see,” Kirby said.

According to reports, the child is Abigail Mor Edan, whose parents were killed in Hamas’ Oct. 7 attack on Israel. Relatives say Abigail survived because her father shielded her with his body. She later made her way to a neighbor’s home, but Abigail and her neighbors were later abducted by Hamas militants, Abigail’s family says.

“We are hoping and praying that she is in one of the first groups, but we only can know that's our hope,” Liz Hirsh Naftali, Abigail’s great aunt, told “CBS Mornings” on Wednesday. "We haven't had any confirmation. We haven't seen any lists. We are going with the belief that because she's 3 years old, and no child should be a hostage, no child should be in this situation, that she will be early in the releasing.”

Kirby said once the hostages are freed, officials will ensure they receive any needed medical attention. 

“We have to assume that they're being held in the most abhorrent conditions and will probably have some physical and maybe even mental health needs,” he said. “We want to make sure that they get that attention. And I'm sure our Israeli counterparts will do everything they can.”

If any American citizens are released, Kirby said U.S. officials would work to quickly reunite them with their relatives, “making sure that their families are there to wrap their arms around them.” Officials would also help facilitate their travel home or wherever else they might want to go, he said.

Kirby said the hostage deal was the result of “weeks of intense diplomacy led by President Biden, who was personally involved in speaking to the leaders of Egypt, Qatar, certainly Israel.”

Qatar played in an integral role in securing the agreement because of its lines of communications with Hamas, Kirby added. 

The NSC spokesman said the deal is not only important because of the hostages’ release, but also because the temporary cease-fire will “create an opportunity to surge additional humanitarian assistance, including fuel into Gaza.”
