United States Vice President JD Vance said Washington would not negotiate with Iran while attacks on commercial shipping in the Strait of Hormuz continue.
"The president's been very clear: We're not talking to them, and we're not going to talk to them unless they stop shooting at commercial shipping," Vance said during a White House news briefing.
Meanwhile, Iran-backed Houthi forces intensified missile and artillery attacks on areas along Yemen's western coast early Thursday, according to media affiliated with government forces and local sources.
Yemen's western coast borders the Red Sea, another critical trade route in the Middle East, while the Strait of Hormuz lies off Iran's southern coast.
The media arm of the Saudi-backed National Resistance said the Houthis launched 14 ballistic missiles towards rural areas around Mokha in Taiz province and south of Khokha in Hodeidah province.
Local residents reported hearing explosions early Thursday in Taiz and Ibb provinces, which they believed were caused by ballistic missiles launched from Houthi-controlled areas towards Yemen's western coast.
A U.S. official confirmed to CBS News on Thursday that Iran's overnight attacks did not hit any military facilities in the Middle East where U.S. forces are based, including Kuwait, which was targeted by Iranian forces.
Iran's army nevertheless claimed it had launched fresh attacks against military bases used by U.S. forces in Kuwait and the United Arab Emirates.
Kuwaiti authorities said Iran had targeted the country with unspecified weapons early Thursday, but did not say whether the attacks were intercepted or caused damage or casualties.
Iran's army claimed it struck U.S. satellite installations, warehouses and fighter jet hangars at Ahmed Al-Jaber Air Base in Kuwait with missiles and attack drones.
It said the strikes were retaliation for U.S. attacks earlier in the week that killed Iranian civilians and military personnel.
The Iranian military claimed the strikes damaged communications systems and fighter aircraft hangars but provided no evidence to support the claims.
It also said radar systems and locations housing U.S. forces at Al Minhad Air Base in the UAE were targeted with missiles and drones. The statement did not claim specific damage from those attacks.
There was no immediate confirmation from the U.S. military that Iranian weapons had struck American facilities in the Middle East on Thursday.
