The United States and Iran-backed Houthi rebels in Yemen are both vowing escalation after the U.S. launched airstrikes to deter the rebels from attacking military and commercial vessels on one of the world’s busiest shipping corridors.
“We’re not going to have these people controlling which ships can go through and which ones cannot. And so your question is, how long will this go on? It will go on until they no longer have the capability to do that,” Secretary of State Marco Rubio told CBS on Sunday. He said these are not the one-off retaliation strikes the Biden administration carried out after Houthi attacks.
President Donald Trump on Saturday vowed to use “overwhelming lethal force” until the Houthis cease their attacks, and warned that Tehran would be held “fully accountable” for their actions.
The Houthi-run Health Ministry said the overnight strikes killed at least 31 people, including women and children, and wounded over 100 in the capital of Sanaa and the northern province of Saada, the rebels’ stronghold on the border with Saudi Arabia.
Trump’s national security adviser, Michael Waltz, on Sunday told ABC that the strikes “actually targeted multiple Houthi leaders and took them out.” He didn’t identify them or give evidence. Rubio said some Houthi facilities had been destroyed.
The Houthis’ political bureau has said the rebels will respond to the U.S. strikes and “meet escalation with escalation.”
The Houthis have repeatedly targeted international shipping in the Red Sea and launched missiles and drones at Israel in what the rebels have called acts of solidarity with the Palestinians in Gaza, where Israel has been at war with Hamas, another Iranian ally. They sank two merchant vessels.
Rubio said that over the past 18 months, the Houthis had attacked the U.S. Navy “directly” 174 times and attacked commercial shipping 145 times with “guided precision anti-ship weaponry.”
The attacks sparked the most serious combat the U.S. Navy had seen since World War II.
The overnight U.S. airstrikes were one of the most extensive attacks against the Houthis since the war in Gaza began in October 2023.
The Houthi attacks stopped when a fragile Israel-Hamas ceasefire took hold in Gaza in January, but last week the rebels said they would renew attacks against Israeli vessels sailing off Yemen after Israel cut off the flow of humanitarian aid to Gaza this month.
There have been no Houthi attacks reported since then.
On Sunday, Iran responded to Trump’s warning and denied aiding the Houthis.
The head of Iran’s paramilitary Revolutionary Guard, Gen. Hossein Salami, denied his country was involved in the Houthis’ attacks, saying it “plays no role in setting the national or operational policies” of the militant groups it is allied with across the region, according to state-run TV.
Iran’s Foreign Minister Abbas Araghchi, writing on X, urged the U.S. to halt its airstrikes and said Washington cannot dictate Iran’s foreign policy.
The U.S. and others have long accused Iran of providing military aid to the rebels. The U.S. Navy has seized Iranian-made missile parts and other weaponry it said were bound for the Houthis.
The United States, Israel and Britain previously hit Houthi-held areas in Yemen, but the new operation was conducted solely by the U.S. It was the first strike on the Houthis under the second Trump administration.
The USS Harry S. Truman carrier strike group, which includes the carrier, three Navy destroyers and one cruiser, are in the Red Sea and were part of the mission. The USS Georgia cruise missile submarine has also been operating in the region.
