The White House announced Sunday that U.S. airstrikes in Yemen have killed several leaders of the Huthi rebel group, and issued a stern warning to Iran to cease its support for the militants and their attacks on Red Sea shipping lanes.

"The strikes specifically targeted and eliminated multiple Huthi leaders," National Security Advisor Michael Waltz said in an interview with ABC News.

In a separate appearance on Fox News, Waltz emphasized the scale of the U.S. response: "We hit them with overwhelming force and put Iran on notice—enough is enough."

Waltz also reaffirmed the U.S. position that “all options are on the table” to prevent Iran from developing a nuclear weapon.

Saturday’s airstrikes—the first U.S. military action against the Huthis since President Donald Trump returned to office—left at least 31 people dead and 101 injured, according to the group's health ministry.

The Huthis, backed by Tehran and in control of much of Yemen for over a decade, are staunchly opposed to Israel and the United States. They claim their attacks on shipping vessels are in protest of Israel’s ongoing military campaign in Gaza.

Since the Hamas-led assault on Israel on October 7, 2023, the Huthis have launched dozens of drone and missile strikes against commercial and military ships in the Red Sea and Gulf of Aden.

According to the Pentagon, U.S. naval forces have faced 174 attacks since 2023, while commercial vessels have been targeted 145 times—disrupting a vital maritime corridor that handles around 12 percent of global shipping traffic.

President Trump, in a strongly worded post on Truth Social on Saturday, addressed Huthi leadership directly: “YOUR ATTACKS MUST STOP, STARTING TODAY. IF THEY DON'T, HELL WILL RAIN DOWN UPON YOU LIKE NOTHING YOU HAVE EVER SEEN BEFORE!”

Last month, Trump sent a letter to Iran’s Supreme Leader, Ayatollah Ali Khamenei, proposing renewed nuclear negotiations. In the letter, Trump warned that without a deal, the issue could be resolved “militarily.”

Iran dismissed the proposal, saying it would not enter negotiations under the threat of force.

Reinforcing the administration’s stance, Waltz said on ABC, “Iran must not acquire a nuclear weapon. All options remain on the table to ensure that outcome.”

“They can either surrender their program in a verifiable way,” he added, “or face serious consequences. But make no mistake, we will not allow a world where the ayatollahs have their finger on the nuclear button.”
