A US military combat drone has been shot down over Yemen, the second time in three months the US has lost a unmanned aerial vehicle over the war-torn country.

Yemen's Houthi insurgency said Wednesday that it downed a US MQ-9 Reaper drone, a $15 million unmanned aerial combat vehicle developed by General Atomics, in Dhamar, southeast of the Houthi-controlled capital of Sanaa.

"We are aware of reporting that a US MQ-9 was shot down over Yemen. We do not have any further information to provide at this time," US Central Command initially said in response to Insider's inquiries.

Two officials speaking to Reuters on the condition of anonymity confirmed the that a drone was shot down. While one said it was the Houthis, another cautioned that it was too early to tell.

"It's the Houthis, but it's enabled by Iran," another US official told Voice of America.

The US military has, to varying degrees, for years been supporting of a coalition of mostly Sunni Arab states, led by Saudi Arabia, fighting to restore the government in Yemen as the Houthi rebels backed by Shia Iran push to topple it.

The Houthis shot down an US MQ-9 in mid-June with what CENTCOM assessed to be an SQ-6 surface-to-air missile. The US believes that the rebel group had help from the Iranians.

"The altitude of the engagement indicated an improvement over previous Houthi capability, which we assess was enabled by Iranian assistance," CENTCOM said in a statement

Around that same time, Iranian forces fired a modified Iranian SA-7 surface-to-air missile at an MQ-9 in an attempt to "disrupt surveillance of the [Islamic Revolutionary Guard Corps] IRGC attack on the M/T Kokuka Courageous," one of the tankers targeted in suspected limpet mine attacks, CENTCOM revealed, USNI News reported at the time. The Iranians failed to down the aircraft.

Toward the end of June, Iranian forces shot down a US Navy Broad Area Maritime Surveillance (BAMS-D) aircraft, specifically a RQ-4A Global Hawk high-altitude long endurance (HALE) drone operating over the Strait of Hormuz, although Iran claims it entered Iranian airspace.

President Donald Trump had initially planned to retaliate militarily but cancelled the mission after learning that striking would result in significant Iranian casualties, which would make the response disproportionate as the Iranians attacked an unmanned system.

Tensions between Iran and the US have spiked in recent months, as Washington put increased pressure on Tehran, leading it to push back with carefully calculated displays of force just below the threshold of armed conflict. The Houthis in Yemen have taken shots at the US before.

The Houthis fired missiles at a US warship in the Red Sea back in 2016, and the US Navy responded by firing on Houthi sites on shore. It marked the first time the US became directly involved militarily in the civil war in Yemen.
