Mecca Alliance activates mutual defense, troops to deploy to Saudi Arabia after Houthi strikes
Saudi Arabia, Türkiye and Pakistan have activated the Mecca Defense Alliance and ordered rapid troop deployments to the kingdom after a wave of Houthi missile and drone attacks. Fighting around the Bab el‑Mandeb Strait, where control is now disputed, threatens a key Red Sea shipping route.
The activation of the Mecca Defense Alliance puts foreign troops on a fast track into Saudi Arabia just as front lines in Yemen shift around the Bab el‑Mandeb Strait, one of the Red Sea’s main chokepoints.
After an emergency meeting in Riyadh on 5 October, the Mecca Alliance announced the immediate activation of its collective defense commitments and “collective deterrence measures” in response to attempted strikes on Mecca and Medina and renewed Houthi attacks on Saudi cities and infrastructure. A joint statement condemned attempted attacks on the holy cities and ongoing strikes on Saudi urban areas, while Houthi forces claimed fresh attacks on targets in Riyadh and other cities.
Pakistan’s Foreign Ministry said Saudi Arabia, Pakistan and Türkiye had agreed under the Mecca Agreement to provide troops and military capabilities, and that these forces would be rapidly deployed on Saudi territory. Saudi Arabia’s defence minister later said the alliance meeting confirmed the activation of collective deterrence against attacks on the kingdom and its holy sites.
The U.S. State Department has kept Saudi Arabia at Level 3 “Reconsider Travel” and maintains a Level 4 “Do Not Travel” warning for areas near the Yemen border, citing risks from missiles, drones and terrorism.
On Yemen’s western coast, the situation remains fluid. On 4 October, Presidential Leadership Council (PLC) President Rashad Mohammed Al‑Alimi announced an operation to regain full control of Yemeni territory. The next morning, Aden‑based forces, primarily the Giants’ Force, launched Operation “Dawn of Yemen” with the aim of recapturing the Bab el‑Mandeb Strait and positions lost in September.
Backed by strong air support, Aden‑aligned units initially broke through around the strategic city of Zubab and by evening were reported to have reached Mocha. According to subsequent accounts, this advance was only on paper: while there were loud statements, no visual confirmation of the full gains had yet emerged.
Sana’a forces then counter‑attacked. Following this pushback, Aden forces were driven back to the vicinity of Al Ardi, and control of Bab el‑Mandeb was described as disputed. At the same time, Houthi‑linked outlets and Iran’s ISNA agency reported that Houthi forces control Bab al‑Mandeb, Dhubab and al‑Mukha, and that they had taken the Taiz governorate residence of PLC president Al‑Alimi.
The PLC’s Presidential Leadership Council forces released video of a unit recently mobilized against Ansar Allah (the Houthis). The footage showed new JAIS Mk2 mine‑resistant ambush‑protected vehicles with Spain‑made Escribano Guardian 2.0 remote weapon stations with M2HB machine guns, supplied by Saudi Arabia. The equipment underscores Riyadh’s role in sustaining the anti‑Houthi coalition on the ground.
Türkiye’s involvement adds another layer. President Recep Tayyip Erdoğan recently said Türkiye is undergoing a “complete revolution” in its defense industry and will keep expanding its capabilities. After Mecca Agreement meetings, Turkish Foreign Minister Hakan Fidan said officials discussed in detail what support could be provided to Saudi Arabia on Yemen and what might be done to help resolve the conflict through peaceful means.
The Mecca Alliance’s activation follows renewed Houthi missile and drone attacks on Saudi territory. One report said the group claimed strikes on targets in Riyadh and other Saudi cities, while another described “coastal setbacks” for anti‑Houthi forces amid these attacks. In parallel, Houthis claimed Bab al‑Mandeb, Dhubab and al‑Mukha were under their control, highlighting the vulnerability of the strait and nearby ports.
For Yemenis, more outside troops and hardware mean an escalation in a war that has already devastated much of the country’s infrastructure and displaced large numbers of people. For residents of Saudi cities such as Riyadh and Jeddah, the alliance promises more visible military activity and air defense operations, along with the risk that further Houthi missiles or drones will target energy facilities or religious sites.
Strategically, the stakes extend to global trade. Bab el‑Mandeb links the Red Sea to the Gulf of Aden and sits on routes for Gulf oil and gas heading to Europe and Asia, as well as container traffic to and from the Suez Canal. Continued combat in and around Dhubab, Mocha or nearby coastal stretches could force shipping companies and insurers to reassess the area, raising costs or prompting calls for more naval escorts.
The next concrete indicators will be evidence of Turkish and Pakistani deployments on Saudi soil, clarification from Riyadh on how Mecca Alliance forces will be used, and any change in reported front lines around Bab el‑Mandeb. Shifts in commercial shipping behavior through the strait and any new Houthi claims of long‑range attacks will show how the alliance’s activation is reshaping the conflict.
