A U.S. F-35 fighter jet had to make an emergency landing in the Middle East just before midnight on Wednesday while flying a combat mission over Iran, according to Capt. Tim Hawkins, a Centcom spokesperson.

The aircraft landed safely at a U.S. base in the region and the pilot is in stable condition. It’s unclear if the stealth fighter was hit by Iranian fire.

This was first reported by CNN.

Iran's foreign minister Abbas Araghchi said Thursday that Iran’s response to attacks on its infrastructure has so far reflected only a “fraction” of its full capabilities.

He added that Iran’s restraint was intended to "respect requested de-escalation," but cautioned that if such attacks continue, Tehran would no longer hold back.

"ZERO restraint if our infrastructures are struck again. Any end to this war must address damage to our civilian sites," Araghchi wrote in a post on X.

The Israel Defense Forces confirmed that it struck a river crossing in southern Lebanon on Thursday, after video widely circulated on social media purportedly shows the Israeli strike hitting just meters away from British journalist Steve Sweeney, a Beirut-based correspondent for state-run Russia Today, while he was was speaking on camera.

RT's editor-in-chef, Margarita Simonyan, who shared the video online, said in social media posts that Sweeney and his cameraman were wounded in the Israeli strike and are both conscious in a hospital.

Simonyan said an IDF aircraft fired on the car carrying the two journalists as they were crossing a bridge in southern Lebanon.

"War journalists are not legitimate targets," Simonyan wrote in a post on X on Thursday.

The IDF said it has targeted Litani River crossings in recent days "that Hezbollah used for both terrorist movement and to transfer thousands of weapons."

"In footage released in the past few hours, a journalist is seen at the 'Qasmiya' crossing," the IDF added in its statement. "An explicit warning had been issued regarding this area. The crossing was struck after sufficient time had passed since warnings."

"The IDF calls on the residents of Lebanon to heed the warnings published on various platforms," the IDF said. "The IDF does not target civilians or journalists and operates in accordance with international law."

More than 1,000 people have now been killed and 2,584 others injured in Lebanon amid ongoing Israeli strikes, according to the Lebanese health ministry.

Of those killed were 118 children, 79 women and 40 health care workers, the ministry said.
