Iran live updates: 7th killed service member is identified

President Donald Trump will attend the dignified transfer of the six U.S. service members killed in this weekend's retaliatory attack by Iran, White House press secretary Karoline Leavitt said Wednesday.

Four of the six have been identified: Capt. Cody A. Khork, 35, of Winter Haven, Florida; Sgt. 1st Class Noah L. Tietjens, 42, of Bellevue, Nebraska; Sgt. 1st Class Nicole M. Amor, 39, of White Bear Lake, Minnesota; and Sgt. Declan J. Coady, 20, of West Des Moines, Iowa. All four died Saturday in Kuwait from an Iranian drone attack.

Coady was among six U.S. troops killed in the first hours of the war with Iran.

Iran's top national security official on Wednesday warned the U.S. and Israel that the killing of Iranian Supreme Leader Ali Khamenei "will exact a heavy price from you."

"Mr. Trump, with Netanyahu's clownish antics, dragged the American people into an unfair war with Iran," Ali Larijani, secretary of Iran's Supreme National Security Council, wrote in a post on X. "Now let him do the math: with over 500 American troops killed (in these past few days), is it still 'America First,' or 'Israel First'? The saga continues."

"The martyrdom of Imam Khamenei will exact a heavy price from you. God willing," he added.

CENTCOM has confirmed that six Americans have been killed in the attacks.

"The evidence in front of us since the 12-day war was that Iran had no intention of actually negotiating a nuclear deal that truly meant they did not have a pathway to the nuclear bomb," Defense Secretary Hegseth said at the Pentagon briefing.

Hegseth said that negotiators Jared Kushner and Steve Witkoff "poured into that negotiation, giving them every single possible opportunity to release that that ambition, and they didn't. And the intelligence that we saw (showed) they didn't intend to do it in good faith - that they had the intentions eventually to get to a place where they could have that a conventional shield to block their nuclear capabilities."

Spanish Prime Minister Pedro Sanchez addressed the nation on Wednesday following President Donald Trump's threat of a full trade embargo after Spain denied the U.S. use of its bases in the war against Iran.

Spain's position, Sanchez said, could be summarized as, "No to war."

The Spanish leader condemned the "indiscriminate" bombing by Iran of other nations in the region. He said that the objectives of the U.S. and Israel were not clear and warned about the "serious consequences" of a potentially long war for the global economy and the cost of living for people in Spain and beyond.

Referring to the 2003 invasion of Iraq and subsequent regional instability, Sanchez said his government's position was based on "not committing the errors of the past."

"No-one" supports the theocratic regime in Tehran, Sanchez said, calling for an end to hostilities and a diplomatic solution "before it's too late."
