Abigail Idan’s aunt, Ella Mor, has asked for privacy for the family as they reunite with the 4-year-old, who was released earlier Sunday after being held hostage since Oct. 7 by Hamas.

“She just landed in the hospital and she’s being checked and taken care of,” Mor said in the video. “I want to thank everybody for all of your love and support. It’s amazing, and thank you so much.

“I just want to say she has family, and we’re taking care of her, so don’t worry about it, and it’s very important to let her be now with the family, and no press and photographs and paparazzi,” she continued. “It’s very important for her safety and health right now, so thank you so much.”

"The Islamic Resistance Movement Hamas is seeking to extend the truce after the end of the four-day period, by seriously considering increasing the number of released detainees as stated in the humanitarian truce agreement," Hamas said in a statement Sunday.

The AFP news agency reported that a source close to Hamas said the group also informed mediators of its willingness to extend the current truce.

President Joe Biden spoke with Israeli Prime Minister Benjamin Netanyahu on Sunday about the latest developments in Gaza, including the release of more hostages, the White House said.

"The President welcomed the release of hostages by Hamas over the past three days, including a young American girl. The two leaders also discussed the pause in the fighting and surge in much needed additional humanitarian assistance into Gaza," the White House said.

The Israeli prime minister's office also issued a statement following their conversation, saying they spoke with "great excitement" about the hostages who were released, including 4-year-old Abigail Idan.

"What a joy to see her with us. But on the other hand, what a pity that she returns to the reality of not having parents. She has no parents -- but she has a whole nation that embraces her and we will take care of all her needs," Netanyahu's office said.
