A Houthi cross-border strike wounded 11 civilians in Saudi Arabia's Najran Province on August 6: 7 Saudi nationals, 1 Yemeni, 2 Egyptian, 1 Pakistani, including a 4-year-old with burns. The wound pattern, dispersed and non-lethal, is consistent with unguided rocket or drone fire into a populated border area rather than a precision hit on hard infrastructure. It continues the Houthi-Saudi exchange that began with Saudi's July 25 strikes on Houthi sites.

The bigger signal came alongside it. Saudi, US, and regional intelligence sources issued a credible, multi-source warning the same day of imminent coordinated strikes: Iraq-based militias from the north, Houthis from the south, both under IRGC coordination, targeting energy infrastructure, ports, and airports. Two-front coordination under Iranian direction is a different signature than routine border harassment. Nothing has hit yet.

The timing lines up with Iran's August 6 publication of a restrictive draft reopening plan for Hormuz, which the US rejected within hours, and the lapse of Trump's August 5 same-day ultimatum without a US strike. Exposure if the warning materializes centers on Saudi east-coast nodes (Abqaiq, Ras Tanura, Yanbu, Jubail) and southern airports near Najran. Watch CENTCOM and UKMTO advisories, Saudi/US air-defense posture, and Iraqi militia statements over the next 24-48 hours.
