Houthis Strike Riyadh Again as Saudi Air Defenses Face Scrutiny

Key points

• Saudi coalition spokesperson Turki Al-Maliki confirmed the interception of one ballistic missile aimed at Riyadh and two directed at Khamis Mushait on Monday night.
• Houthi military spokesman Yahya Saree stated that King Khalid International Airport was the primary target, while a drone was sent toward a military airbase in Khamis Mushait.
• King Khalid International Airport remains closed until Saturday after a Saturday attack killed at least 13 people and wounded over 300, with a Sunday strike killing one and wounding 11.
• Saudi authorities are investigating why air defenses failed to stop previous barrages, with initial inquiries suggesting Houthis used drones to clear a path for missiles.
• Houthi officials warned that US involvement would trigger swift retaliation against American interests in the region, while US President Trump criticized the group but offered no immediate intervention plan.

Background

This escalation follows a series of Houthi strikes on Saudi infrastructure in late September and early October, including a major barrage on oil sites and a deadly attack on Riyadh airport on October 11 that killed 12 people. These events occur amid broader regional tensions linked to the US-Israel war on Iran and a naval blockade of the Strait of Hormuz, which has significantly impacted global oil prices and travel routes.

Why it matters

The sustained attacks on Saudi Arabia’s capital and key infrastructure highlight the vulnerability of regional air defense systems against advanced Houthi weaponry. The closure of major airports and the cancellation of flights by carriers like Etihad and Gulf Air disrupt global travel and economic activity, while the ongoing investigation into defense failures may influence future security strategies in the Gulf. Additionally, the threat of US involvement could further destabilize the region, potentially drawing Washington into direct conflict with Iran-backed forces.

What to watch

Saudi authorities are expected to release findings from their air defense investigation, which may lead to adjustments in military strategy. Airlines will likely resume flights to Riyadh only after the airport reopens on Saturday, pending security assessments. Houthi officials have warned of continued strikes on Saudi oil and airport facilities, while the US may reconsider its stance on supporting Saudi strikes against the Houthis if the situation escalates further.
