US President Donald Trump launched large-scale military strikes against Yemen’s Houthis on Saturday over the group’s attacks against Red Sea shipping.

The Iran-backed group said early Sunday that at least 31 people had been killed so far, at the start of a campaign expected to last many days.

Trump also warned Iran, the Houthis’ main backer, that it needed to immediately halt support for the group. He said if Iran threatened the United States, “America will hold you fully accountable and, we won’t be nice about it!”

The unfolding strikes — which one US official told Reuters might continue for weeks — represent the biggest US military operation in the Middle East since Trump took office in January. It came as the United States ramps up sanctions pressure on Tehran while trying to bring it to the negotiating table over its nuclear program.

“To all Houthi terrorists, YOUR TIME IS UP, AND YOUR ATTACKS MUST STOP, STARTING TODAY. IF THEY DON’T, HELL WILL RAIN DOWN UPON YOU LIKE NOTHING YOU HAVE EVER SEEN BEFORE!” Trump posted on his Truth Social platform.

At least 13 civilians were killed and nine injured in US strikes on Yemen’s capital Sanaa, according to the Houthi-run health ministry. In the northern province of Saada, the Houthi-run Al-Masirah TV said at least 11 others, including four children, had been killed, and 14 injured.

The Houthis’ political bureau described the attacks as a “war crime.”

“Our Yemeni armed forces are fully prepared to respond to escalation with escalation,” it said in a statement.

Images online showed plumes of black smoke over the area of the Sanaa airport complex, which includes a sprawling military facility. The Houthis also reported airstrikes early Sunday on the provinces of Hodeida, Bayda, and Marib.

Residents in Sanaa said the strikes hit a building in a Houthi stronghold.

“The explosions were violent and shook the neighborhood like an earthquake. They terrified our women and children,” one of the residents, who gave his name as Abdullah Yahia, told Reuters.

Another strike on a power station in the town of Dahyan in Saada led to a power cut, Al-Masirah TV reported early on Sunday. Dahyan is where Abdul Malik........
