After eight consecutive days of U.S. strikes on Iran, Energy Secretary Chris Wright said Sunday that the United States’ “mission will go on” until President Donald Trump achieves his war goals.

“The president's mission is essential for peace in the Middle East and peace in the world, and that is to prevent Iran from achieving nuclear weapons, and to degrade their ability to terrorize their neighbors and the world and global commerce. So yes, this mission will go on until the mission is done,” Wright said in an interview on ABC News' “This Week.”

The latest round of strikes came Saturday after U.S. Central Command announced that two American service members were killed, and one other was still missing, after an Iranian attack in Jordan.

“It's tragic to lose American lives, but this is a mission that will save countless lives going forward,” Wright said, when pressed on whether the president planned to retaliate further in response to those deaths.

Since the war started in late February, 16 U.S. troops have been killed, and hundreds have been wounded, according to the Department of Defense.

The International Atomic Energy Agency said on Sunday that it was "looking into reports of an overnight attack on the construction site of a planned nuclear power plant in Darkhovin, Iran," after Iran's Atomic Energy Organization alleged a U.S. strike on the site.

"The facility is in the very early stages of construction and contained no nuclear material when last visited by the IAEA," the IAEA said in a statement posted to social media.

The reported attack "is not believed to pose any radiological risk," the IAEA said, adding that IAEA Director-General Rafael Grossi reiterated his call for "military restraint in the vicinity of all nuclear-related sites."

U.S. Central Command has not yet commented on the alleged overnight attack.

The U.S. Embassy in Amman, Jordan, said in a post to X on Sunday morning that Jordanian authorities evacuated the international airport and seaport in the Red Sea city of Aqaba "due to a specific and credible threat."

"We strongly advise all Americans to refrain traveling to either the airport or seaport. Continue to follow all Jordanian authorities' security directives," the embassy wrote. "U.S. Embassy Amman continues to advise all Americans to avoid travel to military bases in Jordan."

But Jordanian government spokesperson Mohammad Al-Momani said in a statement carried on Jordanian state media and social media on Sunday that no evacuation orders had been issued by the authorities at Aqaba airport or the port. No threats had been recorded, the spokesperson added.
