Saudi Arabia warns it will react 'firmly' to Houthi attacks following missile strikes

Saudi Arabia issued a stern warning on Tuesday, September 15, 2026, stating it will respond "firmly" to defend national sovereignty following a large-scale wave of Houthi ballistic missile and drone strikes targeting southern and western regions of the Kingdom that wounded 13 civilians.

What triggered Saudi Arabia's stern warning and retaliatory strikes?

According to statements from the Riyadh-led military coalition, Houthi forces launched dozens of drones and ballistic missiles on Monday night into Tuesday morning, targeting King Khalid Airbase in Khamis Mushait, as well as positions in Abha and Taif. Local residents in Khamis Mushait reported intense detonations that sparked long-lasting fires, while Saudi civil defense authorities briefly issued air-raid warnings across six regions.

In response, Saudi aircraft executed more than 50 retaliatory strikes against Houthi strongholds in Yemen for the second consecutive day. Hazem al-Assad, a member of the Houthi politburo, declared that attacks against Saudi infrastructure "will continue and escalate" as long as coalition operations persist. Meanwhile, Yemeni government forces reported heavy ground combat in southwestern Taiz province, claiming to have recaptured tactical positions and killed 10 Houthi fighters.

How are wider US-Iran diplomacy and regional security evolving?

The cross-border escalation comes as broader regional diplomacy faces friction. On Monday, US President Donald Trump signaled on Truth Social that Washington is open to talks with Tehran, writing that the US "will choose to engage" if terms align. However, Iran's top security chief Mohsen Rezaei rejected the posture on X, stating no negotiations will occur until Iran's core conditions are met. Iranian Foreign Ministry spokesman Esmaeil Baqaei also denied Iranian control over Houthi actions, describing the group as independent actors operating in their own self-interest.

To coordinate regional security, Saudi Crown Prince Mohammed bin Salman received US Central Command chief Admiral Brad Cooper in Jeddah on Monday, according to the Saudi Press Agency (SPA). The Crown Prince is also scheduled to hold bilateral talks with Egyptian President Abdel Fattah al-Sisi in Cairo. Meanwhile, the International Organization for Migration (IOM) updated its displacement tally, confirming that renewed fighting along Yemen's Red Sea coast has forced 93,864 civilians to flee their homes.
