Iran live updates: 7th killed service member is identified

Secretary of State Marco Rubio spoke with his counterparts in Saudi Arabia, Turkey, Cyprus and Italy on Wednesday about the situation in Iran and the Middle East, according to his spokesperson.

Rubio thanked Saudi Foreign Minister Prince Faisal bin Farhan Al Saud for Saudi Arabia's response to the attack this week on the U.S. Embassy in Riyadh, according to Rubio's spokesperson.

"They also discussed the continued threats the Iranian regime poses to regional stability, as well as other developments in the region," the spokesperson said.

Rubio told Turkish Foreign Minister Hakan Fidan "that attacks on Turkey's sovereign territory were unacceptable and pledged full support from the United States," the spokesperson said.

On his calls with Cypriot Foreign Minister Constantinos Kombos and Italian Foreign Minister Antonio Tajani, the leaders "reaffirmed the strong partnership" between the two countries, the spokesperson said.

White House press secretary Karoline Leavitt said U.S. ground troops in Iran are "not part of the plan" at present.

"They're not part of the plan for this operation at this time, but I certainly will never take away military options on behalf of the president of the United States or the commander in chief, and he wisely does not do the same for himself," Leavitt said at a press briefing Wednesday afternoon.

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.
