Mojtaba Khamenei chosen as Iran's next supreme leader, Iranian state media reports

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.

Mohammad Bagher Ghalibaf, speaker of Iran's parliament, addressed Iran's neighboring countries on Wednesday, saying that Tehran uses its missile and drone capabilities "solely for legitimate defense" against American and Israeli targets.

In a post on X, he expressed hope that with the resolution of the war, the region can "return to days of cooperation and companionship.”
