DUBAI, United Arab Emirates (AP) — Yemen's Houthi rebels shot down what they described as an American drone early Friday, potentially the latest downing of a U.S. spy drone as the militants continue their attacks on the Red Sea corridor.

The U.S. military acknowledged the videos circulating online showing what appeared to be a flaming aircraft dropping out of the sky and a field of burning debris in what those off-camera described as an area of Yemen's al-Jawf province. The military said it was investigating the incident, declining to elaborate further.

It wasn't immediately clear what kind of aircraft was shot down in the low-quality night video. The Houthis, in a later statement, claimed to have downed an American MQ-9 Reaper drone.

The Houthis have surface-to-air missiles — such as the Iranian missile known as the 358 — capable of downing aircraft. Iran denies arming the rebels, though Tehran-manufactured weaponry has been found on the battlefield and in sea shipments heading to Yemen for the Shiite Houthi rebels despite a United Nations arms embargo.

The Houthis have been a key component of Iran's self-described “Axis of Resistance" during the Mideast wars that includes Lebanon's Hezbollah, Hamas and other militant groups.

Since Houthis seized the country’s north and its capital of Sanaa in 2014, the rebels have shot down MQ-9 Reaper drones in Yemen in 2017, 2019, 2023 and 2024. The U.S. military has declined to offer a total figure for the number of drones it has lost during that time.

Reapers, which cost around $30 million apiece, can fly at altitudes up to 50,000 feet (15,240 meters) and have an endurance of up to 24 hours before needing to land. The aircraft have been flown by both the U.S. military and the CIA over Yemen for years.

The Houthis have targeted more than 90 merchant vessels with missiles and drones since the Israel-Hamas war in the Gaza Strip started in October 2023. They seized one vessel and sank two in the campaign that has also killed four sailors. Other missiles and drones have either been intercepted by a U.S.-led coalition in the Red Sea or failed to reach their targets, which have also included Western military vessels.

The rebels maintain that they target ships linked to Israel, the U.S. or the U.K. to force an end to Israel’s campaign against Hamas in Gaza. However, many of the ships attacked have little or no connection to the conflict, including some bound for Iran. The tempo of the Houthi sea attacks also has waxed and waned over the months.

In October, the U.S. military unleashed B-2 stealth bombers to target underground bunkers used by the Houthis.
