Israel-Gaza updates: US making progress toward escape for Americans in Gaza

White House national security council spokesman John Kirby explained during a briefing what the U.S. meant by wanting a "temporary pause" in the action.

"As Secretary [of State Antony] Blinken said, we do think that there should be consideration made right now for humanitarian pauses," Kirby said. "These are localized, temporary, specific pauses on the battlefield so that humanitarian assistance can get in to people that need it or the people can get out of that area in relative safety. That's what a humanitarian pause is, and we think it's an idea worth exploring."

"Now, it could also be more than one spot, right?" he added. "So, I mean, it depends, but we think it's a valuable idea that's worth looking at to help alleviate the humanitarian suffering in Gaza."

Kirby said 74 trucks carrying humanitarian aid have entered Gaza since the Rafah border crossing was opened on Oct. 21, but added it was "not enough." Twelve trucks have crossed with supplies in the last 24 hours, he said.

The U.S. will be sending its two Israeli-made Iron Dome air defense systems to Israel, the Pentagon said Thursday.

"We're also planning to provide the two U.S. Iron Dome systems currently in our inventory to Israel to help further bolster their air defense capabilities and protect citizens from rocket attacks," Brig. Gen. Pat Ryder told reporters today at his briefing.

Ryder said he would not provide delivery timelines due to operational security and would only say that all of the air-defense systems being sent by the U.S. would be "online soon."

Ryder also told reporters that 900 U.S. troops have been deployed or will be deploying to the Middle East, making care to say they will not be going to Israel itself. This includes the THAAD air defense unit, the Patriot missile systems and an air-defense headquarters -- some of which were part of the original 2,200 placed on Prepare to Deploy Orders a few weeks ago.

State Department spokesperson Matt Miller said the U.S. was continuing "close consultations with both the Israeli government and the Egyptian government as well as the United Nations" on opening the Rafah border crossing to American citizens, but that those still talks hadn't crossed the finish line yet.

"We have been making progress. I can't get into the details of that progress because they are very sensitive negotiations, but it's something that we are focused on and hope to have American citizens and other foreign nationals able to move through in the coming days," Miller said.

Miller said the State Department sent a message to American citizens Wednesday telling them that they were continuing "to work out a solution." And while the administration still hasn't given an estimate on how many Americans it is in contact with in Gaza, for the first time Miller said the State Department was speaking with "several hundred."

The Israel Defense Forces claim to have killed the co-architect of the Oct. 7 terror attack in an aerial strike.

IDF fighter jets struck Shadi Barud, the head of intelligence relations for Hamas, the Israeli military said in a statement Thursday. The statement did not specify when the attack occurred.

IDF accused Barud of planning the attack with Yahya Sinwar, the leader of Hamas in Gaza.
