"While we're celebrating Natalie's return, we remember the 239 hostages, among them babies, children, women, and the elderly, who are still held by Hamas in Gaza. This week, family members of those still held hostage by Hamas will be in Chicago to share their stories and call for their immediate release," Cohen's statement continued.

Raanan, 18, and her mother, Judith Tai Raanan, 59, were kidnapped by Hamas during the Oct. 7 massacre in Israel. They were held for nearly two weeks before they were released. Two Israeli women were released last week. More than 200 people are still being held hostage by Hamas.

One million people were pushed from the north of the Gaza Strip towards the south in the last three weeks, according to Philippe Lazzarini, the commissioner general for the United Nations Relief and Works Agency for Palestine Refugees.

This represents half of the population of Gaza, according to Lazzarini.

"I have said many times, and I will say it again, no place is safe in Gaza," he said during a briefing Monday.

Over 670,000 displaced people are currently in overcrowded UNRWA schools and buildings, according to Lazzarini.

The last planned U.S. charter flight out of Tel Aviv's Ben Gurion Airport is set for Tuesday, according to the State Department.

"Commercial availability remains limited out of Ben Gurion Airport," the State Department said. "Please go to Ben Gurion International Airport, Terminal 3 if you wish to depart Israel. U.S. Embassy personnel will be present to direct you and provide specific flight information. Be prepared to wait."

State Department spokesperson Matt Miller said the chartered flights are ending because there's no longer enough American passengers to fill them.

"It is purely a demand issue. We had a charter flight yesterday that had five people on it," he said Monday. "We've consistently seen the demand for our charter flights go down to where we had a lot of flights going out with 50% capability. I think the number of seats that we have offered, we have had something like 25% of that actually be filled."

"We have notified everyone that the charter flight tomorrow is the last one that we are currently planning, so if they do want to leave, now's the time to do it," he continued. "But we will always conduct assessments in real time about whether there's additional demand, whether circumstances change on the ground, and if we need to make additional arrangements, we will of course be open to doing so."

State Department spokesperson Matt Miller said Hamas was making "a number of demands" for opening the Rafah border crossing between Egypt and Gaza to foreign nationals, including the 500 to 600 Americans who are trapped in Gaza.

"Hamas is making a number of demands before they’ll allow people to leave Gaza. I’m not going to speak to those demands, but it's something we're continuing to try to work through," he said.
