Middle East updates: Israel-Lebanon ceasefire extended to Feb. 18

A joint statement from the Israel Defense Forces and the Israel Security agency confirms that the four newly released hostages have been “reunited with their parents” in southern Israel and “will undergo an initial medical assessment” at a local hospital.

"The four returning hostages - Daniella Gilboa, Liri Albag, Naama Levy, and Karina Ariev - have arrived at the initial reception point in southern Israel where they are being reunited with their parents," the statement said.

"IDF officers from the Manpower Directorate and IDF medical officials are accompanying the returning hostages, and they will undergo an initial medical assessment. IDF representatives are accompanying their families waiting at the hospital and updating them with the latest available information."

Israel Defense Forces spokesperson, Rear Adm. Daniel Hagari, gave a televised statement Saturday morning, in which he confirmed that the four female IDF soldiers who were just released from captivity in Gaza are now meeting with their parents in Israel.

Hagari said Hamas failed to meet its commitment to the agreement for Saturday to also release civilians and that they must free Yehud Arbel and Agam Berger.

He said the IDF also expects them to release Shira Bibas and her children, saying there’s grave concerns about their wellbeing.

He called the event in which Hamas brought the hostages onto a stage in a crowded square in Gaza City before releasing them a “cynical” show.

The Four returning hostages -- Daniella Gilboa, Liri Albag, Naama Levy and Karina Ariev -- have crossed into Israeli territory with IDF and ISA Forces, according to a statement from the Israel Defense Forces and the Israel Security Agency.

"A short while ago, accompanied by IDF and ISA forces, the four returning hostages crossed the border into Israeli territory," the statement read. "The returning hostages are currently on their way to an initial reception point in southern Israel, where they will be reunited with their parents."

Four female hostages, who appeared to be wearing IDF uniforms and carrying paper bags, were just escorted by Palestinian fighters out of vehicles to a stage in the square, where they were seen smiling and waving at the cheering crowd. They were then escorted into the Red Cross vehicles, which are now slowly driving out of the crowded square.

"The Israeli government embraces the four returning Israel Defense Forces soldiers," according to a statement from the Israeli Prime Minister’s Office. "Their families have been informed by the designated authorities that they have joined our forces. The Israeli government is committed to the return of all abducted and missing persons."
