The Houthis launched a complex attack consisting of anti-ship missiles and drones, a Pentagon spokesperson said Tuesday.

For more than a year, U.S. warships have shot down Houthi drones and missiles, but the rebels continue to menace shipping in the Red Sea.

The US Navy confirmed that at least eight drones, five anti-ship ballistic missiles, and three anti-ship cruise missiles were launched at the USS Stockdale and the USS Spruance on Monday (Nov 11).

The attack on the ships was the latest in months of violence in the region by the Yemen rebels, who are backed by Iran and have targeted commercial shipping as well as the U.S. naval forces deployed to the region.

Houthi rebels used missiles and drones to attack the American aircraft carrier Abraham Lincoln in the Arabian Sea. They also reportedly struck two American destroyers in the Red Sea, according to a military representative of the radical organization,
