Saudi civil defence sent overnight phone alerts to Riyadh and Al-Kharj warning of potential aerial attacks before issuing an all-clear Saturday morning, the first such alerts since the Houthi escalation began in July.
A large black smoke plume rose near Riyadh's main airport Saturday, with Reuters footage showing flames behind what appeared to be fuel tanks and booms heard across the Olaya district; the Saudi government's media office did not immediately respond to questions about the cause.
The Houthis declared a naval blockade against Saudi Arabia in July and have since struck Saudi cities, energy infrastructure, Red Sea shipping, and vessels, endangering the main alternative export route while the Strait of Hormuz remains blockaded.
Houthi military spokesperson Yahya Saree on Friday vowed a response, blaming Saudi Arabia for unspecified "criminal attempts" in Sanaa that the group claimed to have foiled.
The UN Security Council on Friday condemned Houthi attacks on Saudi Arabia — including strikes on civilian and energy infrastructure that injured civilians including women and children — and separately condemned "Houthi military escalation in Yemen."
The Houthis, who seized Yemen's entire Red Sea coast in a lightning advance this month, say the Saudi Air Force has conducted hundreds of airstrikes against them in recent days.

Why it matters: Overnight Riyadh alerts and visible damage near the capital's main airport — including apparent fuel tanks — represent a direct escalation of Houthi cross-border strikes into Saudi Arabia's heartland, putting Gulf energy infrastructure and Red Sea shipping at renewed risk on top of the ongoing Strait of Hormuz blockade. The UN Security Council's Friday condemnation diplomatically isolates the Houthis, but with the group now controlling Yemen's entire Red Sea coast and pledging retaliation, Saudi civilian and oil assets face a sustained threat.
