Deadly Riyadh Airport Attack Highlights Iran's Culpability in Outsourced Houthi Violence

The tragic deaths of at least 12 people and injuries to over 300 others in Saturday’s devastating attack on Riyadh’s King Khalid International Airport serve as a stark reminder of the severe threat posed by Yemen’s Houthi militia. The victims included Saudi and foreign citizens who were simply traveling, working, or worshiping. An airport meant to provide safe passage was transformed into a site of terror. While the Houthis bear direct responsibility for this atrocity, Iran is also deeply culpable for the support it provides to the rebels.

For years, Iran has utilized a strategy of forward defence by cultivating armed proxies to project power beyond its borders. Although Tehran and its regional allies have faced setbacks, the Houthis' capacity to strike civilian infrastructure with missiles and drones demonstrates the ongoing danger of these networks. This military backing directly contradicts recent statements from figures like President Masoud Pezeshkian, who has emphasized the importance of regional engagement, and former foreign minister Mohammad Javad Zarif, who questioned the hardline approach toward the outside world.

However, diplomacy cannot succeed while leaders in Tehran continue to support a militia that represses people in Yemen and targets civilians overseas. Rather than providing leverage, Houthi escalation invites retaliation, undermines trust among Gulf neighbours, and fosters an increasingly unpredictable and dangerous regional environment. Saudi Arabia maintains the full right to defend its population, and if Tehran genuinely seeks to improve relations with its neighbors, it must halt its military support for the Houthi campaign.
