Muhammad Ibrahim Asfour was among the Gaza residents who returned home during the cease-fire to find destruction where homes used to be.

"I was shocked, and when I saw the house I started crying," Asfour told ABC News. "There were 50 people in the building here -- all of my brothers and father were living here."

"The situation here is more difficult than you can imagine," Abdelkader Darma told ABC News. "When I came home I was shocked."

"People do not know where to go," Darma said. "I and six other people slept on two mattresses and two pillows, which means you do not know how to sleep. They sleep three against three, and you find his feet in front of your face."

“I hope the truce will be extended and a solution will be found because it is enough. People are sleeping in the street," Darma said. "How can you bear it?"

Israel and Hamas reach agreement to extend truce for 2 more days

Qatari officials announced the extension with Hamas, saying the truce is "under the same conditions as the previous" agreement.

Hamas said this truce is "under the same conditions as the previous truce."

Diaa Rashwan, chairman of Egypt's State Information Service, said earlier on Monday that the deal would involve the release of 10 Israeli women and children being held hostage by Hamas in exchange for 30 Palestinians detained in Israeli prisons each day of the extension.

Alma Avraham, an 84-year-old Israeli hostage freed by Hamas on Sunday, remains hospitalized in critical condition, Israeli officials said Monday.

She suffers from preexisting conditions and was receiving regular medication before she was kidnapped, said Dr. Tzachi Slotsky, deputy administrator of Soroka Medical Center.

"If she hadn’t been transferred to us yesterday, or any other delay in her transfer, it would’ve worsened her condition even more," Slotsky said. "She is intubated and sedated at the emergency room and her life is still in danger."

Without care, she soon would have died, said Avraham's daughter, Tali Amano.

"My mother did not deserve to return this way -- my mother was medically neglected," Amano said. "She didn’t get any of her medication."

"The only reason we are standing here today ... is to save those who are left there [in Gaza]," Amano said.

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."
