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.

State Department spokesperson Matt Miller claimed Monday that the U.S. was making "significant progress" on getting fuel into Gaza via a "reliable delivery mechanism" that would assuage Israel's fear that it could be intercepted by Hamas.

"Fuel is essential to the delivery of humanitarian assistance, the desalinization of water and the provision of medical care and we want to see it provided for those purposes as soon as possible," Miller said. "I should note that even as we work to provide fuel for these essential humanitarian services, Hamas continues to maintain extensive fuel reserves. Rather than provide that fuel to hospitals or aid workers or for other civilian needs, however, it continues to hoard it for the benefit of its fighters and to carry out its terrorist attacks against Israel."

"We aim to surpass that number today, tomorrow and beyond," Miller said Monday.
