A Houthi attack on Riyadh's international airport has raised questions about whether the alliances Saudi Arabia has been building — both longstanding and newly formed — can provide adequate protection without drawing the broader region into the conflict. Figures released by Saudi civil aviation authorities put the death toll at 12, with a further 309 people sustaining injuries in the assault.
Notices issued by the Houthis have called on airlines, travellers, and airport personnel to avoid Saudi airspace and its associated airports. The consequences of the attack extend beyond the casualty figures. On Sunday, Riyadh's airport halted operations and carriers pulled or suspended their scheduled services after the Houthis declared that Saudi airspace had become an active zone of military activity.
On October 10, a third consecutive assault on the airport unfolded within that same seven-day span. Three fatalities — among them a pilot from Saudi Arabia — were recorded in attacks that struck the same location beforehand. Statements from Houthi representatives have put Saudi energy infrastructure on notice as a potential target.
Renewed hostilities have drawn Saudi Arabia back toward a conflict the country had devoted considerable effort to stepping away from. Hostilities between the Houthis and Saudi Arabia had been on pause under a 2022 ceasefire agreement, though armed activity picked up again by July. In the period that followed, Houthi forces extended their territorial hold along the Red Sea coastline of Yemen.
Troops aligned with Yemen's internationally recognised government mounted a counter-push, drawing on aerial cover and broader material support provided by Saudi Arabia. Forces aligned with the Yemeni government reported recapturing key positions along the Bab el-Mandeb Strait, though the Houthi movement contests those accounts and the true scope of any territorial shift has yet to be independently verified.
A coalition spokesperson put the number of aircraft involved at 100 and the tally of high-value targets destroyed at 324, though as of Sunday neither figure had been confirmed by any independent source. Perim Island and nearby coastal zones are among the areas where Houthi fighters assert they have established a foothold close to the strait, a claim that armed forces aligned with the government dispute, saying their troops have regained ground.
Linking the Gulf of Aden to the Red Sea and onward to the Suez Canal, the Bab el-Mandeb strait serves as a navigational passage between those three bodies of water. Positioned along the strait's edge, the group retains enough reach to observe vessel movements and place maritime traffic under threat, yet lacks the kind of grip over the waterway that would allow it to halt ships altogether.
Defending urban centres and energy installations at home while lending support to an offensive aimed at reclaiming a strategically positioned waterway presents a dual burden for Saudi authorities. Analysts have identified competing options in how Saudi Arabia frames its response. Some analysts contend that a restrained posture could leave gaps in air defence coverage while also weakening the deterrent signal that the newer partnership arrangements were designed to send. Analysts have also noted that broadening the scope of operations carries the prospect of extending hostilities and exposing Saudi forces along with their allied partners to heightened battlefield risks.
The Mecca Joint Defense Agreement, binding Turkey and Pakistan together with Saudi Arabia, represents one strand within that broader strategic calculus. A trilateral agreement took effect after all three nations put their signatures to it during August. A statement released by the joint committee on October 5 outlined plans to activate collective-defence obligations and deploy agreed military assets to Saudi Arabia under a rapid-response framework. No timeline was set out and the forces involved went unnamed, leaving the practical mechanics of how the pledge would be carried out unaddressed.
Ankara has characterised the agreement as serving a purely protective purpose. Citing government officials as its source, one broadcaster framed the anticipated Turkish involvement as limited to technical assistance and defensive measures. Key details — including a deployment timeline, troop numbers, and a command structure — were not specified when the plan was put forward.
What the arrangement will ultimately produce — and whether either party will enter the conflict in Yemen — remains an open question. Signing on to a mutual-defence arrangement carries no inherent obligation to take part in offensive military action.
Red Sea shipping lanes represent the most direct point of exposure for Israel in this context. Ongoing threats to vessels in the area have left direct commercial shipping routes to Eilat without regular service from international carriers. Clashes around Bab el-Mandeb have drawn renewed attention to how, and whether, the port can rebuild its operations. Goods moving through Aqaba, Jordan, have restored a measure of trade activity, though the overland corridor itself remains closed.
Risks to maritime passage represent an active concern for Israel on both economic and defence grounds, independent of how relations with Saudi Arabia develop. Separate reporting by outlets in Israel has pointed to intelligence-sharing arrangements — or at minimum, discussions about such arrangements — between Israel and Saudi Arabia conducted by way of US Central Command. Sourced from regional diplomatic and security contacts, the information in those reports has not been formally acknowledged by either government involved. Those arrangements do not constitute a formal alliance, nor do they involve direct participation by Israeli forces in the conflict.
The strike on Riyadh has placed the country's air defence network — still developing its operational depth — under a level of scrutiny it had not previously faced. The question facing Riyadh is whether it can keep urban centres and supply routes intact, recover territory lost to Houthi forces, and do so without the offensive drawing neighbouring states into the fighting. Eilat's reliance on Red Sea shipping lanes means the port city stands to be affected by broader disruptions to those routes.
