The US military says it has hit more than 800 targets since launching sustained air and naval strikes against the Houthi movement in Yemen on 15 March.
In a statement summarising recent operations, US Central Command said it had “killed hundreds of Houthi fighters and numerous Houthi leaders”.
Washington has said it is acting to end the threat the Iran-backed Houthis pose to shipping in the Red Sea and the Gulf of Aden.
US military said weapons storage and manufacturing facilities had been among targets it had struck, but said it would not “reveal specifics” about ongoing operations.
The US said it “would continue to ratchet up the pressure” until Houthi attacks on vessels are halted.
In Yemen, the Houthis, who control large swathes of the country, said the latest US attack on the capital Sanaa on Sunday killed at least eight people, including women and children.
Earlier this month, the Houthi-run health ministry said US air strikes on a Red Sea coast controlled by the Houthis killed at least 74 people and wounded 171 others.
Last month, Trump ordered large-scale strikes on areas controlled by the Houthis and threatened that they would be “annihilated”.
He has also warned Iran not to arm the group – something it has repeatedly denied doing.
Since November 2023, the Houthis have targeted dozens of merchant vessels with missiles, drones, and small boat attacks in the Red Sea and the Gulf of Aden. They have sunk two vessels, seized a third, and killed four crew members.
