President Joe Biden said Liat Beinin Atzili, an American-Israeli dual national who was one of 16 hostages released from Gaza on Wednesday, is "safe" in Egypt and that he has spoken to her parents.

"I've got some very good news to report. Liat Beinin is safe in Egypt. She's crossed the border," Biden told reporters as he was boarding Air Force One in Pueblo, Colorado.

"I talked with her mother and father and they're very appreciative and things are moving well," Biden said. "She'll soon be home with her three children. That's all I have to say for right now."

The president did not respond when asked for an update on other Americans who might be released.

Sixteen hostages were released from Gaza on Wednesday.

Ten hostages were released in exchange for 30 Palestinian prisoners, according to the Qatari foreign minister, just before the truce was set to expire.

Among the 10 hostages exchanged for the Palestinian prisoners was 49-year-old Liat Beinin Atzili, an American-Israeli dual national.

The other released Israeli hostages were: 13-year-old Gali Tarshanksy, 17-year-old Ofir Engel, 54-year-old Raaya Rotem, 57-year-old Raz Ben Ami, 36-year-old Yarden Roman, 16-year-old Amit Shani, 18-year-old Itay Regev, 40-year-old Stela Yanai and 18-year-old Liam Or.

In addition, two Russian-Israeli citizens and four Thai citizens were also handed over to the Red Cross outside the framework of the agreement, the Qatari foreign minister said.

According to officials, 145 people remain hostages.

Ambassador Linda Thomas-Greenfield, the U.S. representative to the United Nations, said the U.S. is "hopeful" that the truce between Israel and Hamas -- set to expire Wednesday night -- will be extended.

Another extension "is all in the hands of Hamas," she said. "The Israelis have said if they continue to release 10 hostages a day, they will extend by a day. So it truly is … it is in their hands. But I do think there is a potential for that, and we're actively working to extend the deal."

"We will not rest until all hostages are free," she continued. "And if Hamas chooses to continue to release hostages, then Israel is prepared to continue the pause in the fighting."

Dania Hanatsheh's name is on a list of 30 Palestinian women, girls and teenage boys expected to be released Wednesday as part of another exchange of Israeli hostages held by Hamas.

The family said Hanatsheh, 21, was arrested on Nov. 21 when Israeli soldiers raided their home in the West Bank.

The Israeli Justice Department said Hantsheh is accused of "supporting terrorism."

Hantsheh's father, Saqer, believes his daughter was arrested because of her social media posts.

"I am proud of my daughter," he told ABC News. "When she posted asking people to stand with Gaza, I support her with that because it's her right to do that."

He said he's looking forward to "hugging my daughter again."

But his happiness is tinged with sadness for the suffering in Gaza.

"The prisoners are getting released, but the price of this is the blood of women and kids in Gaza," he said.

Yifat Zailer, a relative of one of the youngest Israeli hostages still being held in the Gaza Strip, said Tuesday that she has yet to hear whether her missing family members will be among those released by Hamas as part of the truce.

"The pain of not having them back yet is incredible. Tomorrow is the last day of this deal of cease-fire and we are very concerned," Zailer told ABC News' George Stephanopoulos in an interview on "Good Morning America."

Zailer said there has been no word from Israeli officials or others on whether her loved ones will be included in the prisoner swap with Hamas. The last thing she heard about her missing relatives was in a recent statement released by the Israel Defense Forces that stated there was a possibility of another Palestinian militant group holding them hostage.

"We are completely at loss," she said. "We don't know about their condition, we don't know if they're still alive even and it’s unbearable. They promised in this deal they signed, all the sides, that all mothers and children are supposed to be released."

"Prisoners are being released," she noted. "Where's my family?"

Four of Zailer's relatives -- her 32-year-old cousin Shiri Babas, Shiri's 34-year-old husband Yarden and the couple's children, 4-year-old Ariel and 10-month-old Kfir -- were kidnapped from their kibbutz in southern Israel during Hamas' attack on Oct. 7 and taken hostage to Gaza. Zailer said she doesn't understand why they -- especially the baby -- are still being held hostage and wondered whether it was for "leverage."

"Kfir is going to be 11 months [old] soon. He was kidnapped when he was 9 [months old]. We don't know how he's being fed," she told ABC News. "Why aren't they on any list? Every night we receive that phone call that they're not coming back tomorrow is torture -- it's psychological torture."

When asked whether she would support a deal for Israel to release all of its Palestinian prisoners in exchange for the hostages in Gaza, Zailer said: "That's a really hard question, but I must say I am."

"All those hostages are fathers, mothers, injured people and, of course, my family members as well among them," she continued. "So there's no price for our loved ones."

Zailer said she wants the world to know that her captive relatives "are and always were people of peace" and "innocent civilians."

"My uncle raised his daughter to love who's different from her," she added. "She's an incredible mother, her husband is an incredible father."
