A US warship faced an attack in the Red Sea, responding by downing three drones.
Commercial vessels, including a UK-owned ship, were also targeted off Yemen’s coast.
The Pentagon stated the attacks posed a direct threat to maritime security, linking them to Houthi rebels in Yemen with alleged Iranian backing.
The rebels claim responsibility for attacking ships, targeting Israeli vessels.
The situation underscores rising tensions in the region, with the Houthis vowing to obstruct Israeli ships until Gaza aggression ceases.
The incident lasted around five hours, involving the USS Carney intercepting at least one drone.
The targeted UK-owned ship, likely the Unity Explorer, was en route from the US to Singapore.
The Houthis continue holding the hijacked Galaxy Leader vessel since November 19.
