Iran live updates: War cost US more than $40B, officials said to lawmakers

The Houthis will continue to fight "the Saudi enemy" and blockade Saudi ships in the Red Sea, the Houthis' military arm said in a statement Friday.

The statement primarily addressed the Saudi claim that the Houthis had targeted the holy city of Mecca. The Houthis called the claim the "Big Lie" and a "monstrous slander leveled against our people."

"We assert our natural right to respond to this aggression through all legitimate means and forms of retaliation, and we authorize our leadership and army to respond in the appropriate manner," the statement read.

Italian Defense Minister Guido Crosetto confirmed on Friday that an Italian Eurofighter Typhoon fighter jet was "hit" during a Thursday night attack on the King Fahad Air Base in southwestern Saudi Arabia.

"An Italian F-2000 aircraft was hit, which was located inside the base in a remote area," Crosetto said in a statement posted to X by the Italian Defense Ministry, using the Italian air force's designation for the Typhoon. "There are no other damages to vehicles or infrastructure used by our personnel."

The air base, Crosetto said, "has been the target of several attacks." Italian troops engaged in Operation Inherent Resolve -- the U.S.-led coalition campaign against ISIS -- are deployed at the facility, which is also known as the Taif air base.

Crosetto did say who was responsible for the strike. The Iranian-backed Houthi rebels in Yemen have claimed multiple drone and ballistic missile attacks on the King Fahad Air Base in recent weeks.

South Korean President Lee Jae Myung on Friday said that Seoul will not engage in the ongoing U.S.-Iran war, as the country weighs plans to contribute to future maritime security operations in the Strait of Hormuz.

"Let it be clear. There will be no dispatch of troops that will lead to involvement in a conflict. There will be no engagement or involvement in war," Lee said in a televised press conference, as quoted by the Yonhap News Agency.

"The principle of no engagement or involvement in war has been observed so far and will continue to be observed in the future," he added.

South Korea has faced pressure from President Donald Trump to provide active support for U.S. military operations against Iran.

Last month, Trump ordered the curtailment of planned joint U.S.-South Korean military drills, a decision he said was in part due to Seoul's refusal to join the conflict.
