In Sanaa, which the Huthis seized in 2014, "American aggression" targeted the international airport and part of the city centre, "damaging houses and businesses", the rebel TV station Al-Masirah said.

It also reported strikes in the Amran, Saada and Jawf regions of the north, as well as in Hodeida in the west and Marib in the east.

A health ministry spokesman said seven people, including two children, were wounded.

On Thursday, the Huthis said similar strikes killed two people and wounded two.

In response, they said they had targeted "warships in the Red Sea, including the American aircraft carrier (USS Harry S.) Truman", as well as Israel's Ben Gurion international airport.

The Israeli military said it intercepted two missiles fired from Yemen.

The United States launched what its Central Command called a "large scale operation" involving air strikes against the Huthis on March 15.

Washington vowed to use overwhelming force until the group stopped firing at vessels in the key commercial shipping lanes of the Red Sea and Gulf of Aden.

The rebels had paused their attacks after a ceasefire took effect in the Gaza war, but had threatened to resume them over Israel's recent aid blockade on the Palestinian territory.

The Huthis have reported near-daily US air strikes on areas under their control since the operation began.

The United States says it has killed several senior Huthi officials.

While Washington does not always report its raids, a US defence official told AFP on Sunday that American forces were "conducting strikes across multiple... Iran-backed Huthi locations every day and night in Yemen".

The Huthis began targeting ships in the Red Sea and Gulf of Aden after the Gaza war began in October 2023, claiming solidarity with the Palestinians.
