All 50 women and children hostages who were in the original swap agreement have been released, Israeli Prime Minister Benjamin Netanyahu said.

"We are obliged to complete this outline and bring about the release of all our abductees -- women and children and later, everyone -- without exception," he said.

The Israel Defense Forces "is prepared to continue fighting" in the Gaza Strip and is "using the days of the pause as part of the framework to learn, strengthen our readiness and approve future operational plans," according to IDF Chief of Staff Lt. Gen. Herzi Halevi.

"The return of the hostages is a bright light for us all," Halevi said in a statement on Tuesday. "It is also further evidence of the results of significant military pressure and resolute ground operations, which created the conditions for the return of our civilians home."

Halevi vowed "to apply the same strength" if needed in northern Israel, where he said some residents have been evacuated from their homes amid clashes along the border between Israeli forces and Lebanese militant group Hezbollah.

"The IDF's ground operations in Gaza City, a dense and complex area, aim to achieve a worthy and necessary goal," he said. "We know, if required, how to apply the same strength in the north, in order to return you safely to your communities, cities and this beautiful and important region of the country."

About 1.8 million Gaza residents -- over 80% of the population -- are now displaced, according to the United Nations.

Nearly 1.1 million of those displaced residents have sought shelter from the United Nations Relief and Works Agency for Palestine Refugees in the Near East.

But the shelters are so overcrowded that they may have just one toilet for every 125 people and one shower for every 700 people, the U.N. said.

Instead of staying at the shelters, many residents are instead camping at the sites of their destroyed homes, the U.N. said.

A French warship has arrived in Egypt's norther port city of El-Arish, near the border with the war-torn Gaza Strip, to serve as a hospital for wounded Palestinians, a diplomatic source told ABC News on Tuesday.

The Dixmude, the first Western military ship to dock in Egypt, has around 40 hospital beds and two surgical operation rooms. The vessel is expected to remain in El-Arish for about a month, the source said.

The ship carries military medics as well around two dozen civilian pediatricians and surgeons. Patients with permits are expected to leave Gaza for Egypt through the Egyptian-controlled Rafah border crossing, before being transported to the Dixmude for medical treatment, according to the source.

From there, patients should be transferred to Egyptian hospitals for later stages of treatment, the source said, but French officials have not yet reached an agreement with Egyptian authorities on that.

Hundreds of demonstrators gathered on Saturday at the first anti-government protest held in Tel Aviv since Oct. 7.

"We don't want a radical government. We didn't want it before, and we don't want it now," Moshe Radman, who helped organize the protest, told ABC News. "We are telling them we want a new government as soon as possible."

Radman says people were scared to protest in the early days of the war -- but that things have changed in the last few weeks. He predicts the demonstrations will grow.

"We gave them 57 days, and week after week we saw that they are not doing the right thing. And I think we understand that we are headed towards a long war, so we have to do it now," he said.

Protesters Sharon and Eyal Eshel said their 19-year-old daughter Roni, an Israel Defense Forces soldier, was killed in the Oct. 7 attack by Hamas militants while stationed at the Nahal Oz kibbutz. Her family said they have yet to receive a single phone call from Israeli Prime Minister Benjamin Netanyahu.

"We are looking for answers, we want answers from the IDF, we want answers from the government. And we want the man who is in charge, we need him to take responsibility," Sharon Eshel told ABC News.

"It's not the time to say, 'It's not the time,'" Eyal Eshel told ABC News, calling on Netanyahu to sit down with him and answer his questions. "Enough is enough."

In response to criticism and pool polling numbers, Netanyahu has previously said he has no plans of stepping down.
