American and British forces shot down 18 drones and three missiles Tuesday that were launched by Yemen's Iran-backed Huthi rebels toward international shipping lanes in the Red Sea, the US military said.

"Iranian-backed Huthis launched a complex attack of Iranian designed one-way attack UAVs… , anti-ship cruise missiles, and an anti-ship ballistic missile from Huthi-controlled areas of Yemen into the Southern Red Sea," the US Central Command (CENTCOM) said in a statement.

The drones and missiles were downed by a combination of F/A-18 warplanes operating from the USS Dwight D. Eisenhower aircraft carrier and one British and three American destroyers, CENTCOM said.
