A Yemen-Based Pact Between al-Qaeda and the Houthis Now Worries Washington

A Wall Street Journal article published this week carries the headline "Washington's Deadly New Headache: an al Qaeda-Houthi Terrorist Alliance." Regional analyst Rashid Abdi flagged the piece on social media, pointing to what the Journal frames as a deepening partnership between Yemen's Houthi movement and al-Qaeda's regional branch, al-Qaeda in the Arabian Peninsula (AQAP).

That framing tracks with what United Nations monitors have already documented. A UN Panel of Experts report from February 2025 described a "covert pragmatic relationship" between the Houthis and AQAP that has widened from shared security intelligence and training into discussions of AQAP support for attacks on maritime targets. The same monitors traced a parallel channel of cooperation running from the Houthis to al-Shabaab in Somalia, including physical meetings in 2024 over transferring weapons and training in exchange for help with piracy and arms smuggling across the Gulf of Aden.

Iran sits behind much of the hardware that makes this network dangerous. U.S. officials and UN monitors say Tehran's Revolutionary Guard Quds Force has supplied the Houthis with weapons, targeting data and military advice since 2015, using an intricate smuggling network to move missile components, guidance systems and drone parts into Yemen despite years of sanctions and coalition bombing. Interdictions have piled up on both sides of the Gulf of Aden: a U.S. Navy seizure of ballistic and cruise missile components northwest of Socotra in January 2024, suicide drones intercepted near Boosaaso in June 2024, and a U.S.-Somali strike on an unmarked vessel carrying weapons near Baraawe in April 2025.

The financial stakes explain why. Shipping agents pay the Houthis an estimated $180 million a month in "safe transit" fees, funneled through hawala networks and shell companies spanning Djibouti, Iran and Turkey, according to UN monitors. Suez Canal traffic has fallen by roughly half since the Red Sea attacks began, container shipping costs have nearly quadrupled, and Egypt's canal revenue is down an estimated $800 million a month. The March 2024 hijacking of the MV Abdullah by Somali pirates, released the following month for a reported $5 million ransom, showed how easily these waters still generate money for armed groups even without a state patron involved — a reminder of the piracy capacity the Houthis are now reportedly helping al-Shabaab revive.

None of this means al-Qaeda has adopted Houthi ideology or that Tehran directly controls AQAP. The relationship UN monitors describe is transactional: Houthi weapons and training in exchange for AQAP's smuggling routes and maritime reach, with Iran's patronage making the whole arrangement viable. But for Washington, and for Gulf states whose energy exports and port investments run through this exact corridor, a Sunni jihadist network and an Iran-aligned militia no longer working at cross purposes is a harder problem than either posed on its own.
