Israel-Gaza live updates: Israeli officials on reports of Russian airport protesters

A missile struck a medical facility in the Egyptian Red Sea resort town of Taba, near the border with Israel early on Friday, injuring six people, Egyptian state-linked Al-Qahera News TV channel reported Friday morning local time.

The missile was fired as part of the ongoing violence in Gaza, it said, citing sources.

The blast, which hit a Taba ambulance facility and a residential building for the staff of the Taba Hospital, damaged a residential building, the station reported. The channel aired footage showing a charred car and big holes in the facade of a building.

"Once the side that launched the missile is identified, all options are available to address and Egypt reserves the right to respond [to the incident] at the right time," a security source from the Egyptian government told the channel.

There was no immediate claim of responsibility.

Earlier this week, a number of Egyptian border guards were injured after being hit by fragments of a shell that Israel said was accidentally fired from an Israeli tank. Israeli Defense Forces quickly apologized for the incident.

A senior U.S. official said Thursday the administration has requested that Israel allow the U.S. to get forces in place before Israel launches an expected ground invasion in Gaza.

The U.S. has also requested that Israel get a better handle on the hostage and humanitarian situation in Gaza, where cases of dysentery from people drinking contaminated water are being reported, the official said.

Additionally, the U.S. told the Israelis that it is still not convinced they have a good plan for what they want to do in Gaza, the official said.

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.
