The family of 4-year-old hostage Abigail Idan has released the first photo of the little girl following her return home from Gaza.

Abigail, an American-Israeli citizen, had been held hostage by Hamas since Oct. 7. She was released on Sunday, two days after her 4th birthday.

Abigail Idan’s aunt, Ella Mor, said in a video Sunday, "She just landed in the hospital and she’s being checked and taken care of."

"I'm so happy that she's here," Mor told ABC News. "The people of Israel are amazing … everybody's so happy like she's their own little girl."

Liz Hirsh Naftali and Noa Naftali, the great aunt and cousin, respectively, of 4-year-old Abigail Idan, issued a statement Sunday following Abigail's release by Hamas.

"We hoped and prayed today would come. There are no words to express our relief and gratitude that Abigail is safe and coming home," they said.

"Thank you to President Biden and his dedicated team; thank you to the Qatari government and other informal actors who are involved in securing Abigail's release and reuniting other hostages with their loved ones," they continued. "Today's release proves that it’s possible. We can get all hostages back home. We have to keep pushing. We will continue to stand with the families of all the hostages still held captive, and we remain committed as ever to securing their safe and swift return."

"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.
