US officials said on the 17th (local time) Iran fired a ballistic missile at a US military base in Saudi Arabia, the first direct Iranian strike on Saudi territory in nearly four months. Saudi civil defense issued warnings for two locations on the 18th and later said the threat had passed.

Bahrain's defense ministry said it intercepted multiple Iranian air strikes on Saturday.

Open-source intelligence group Faytuks Network reports Iran has stepped up missile strikes on US bases over the past week. Most missiles were intercepted and most Gulf bases sustained only minor damage, but strikes in Jordan have been more persistent and damaging. Despite interceptions, missiles have hit Jordanian targets nearly nightly since the escalation, a pattern that may indicate local air defenses are approaching saturation and interceptor shortages, which would reduce per-shot intercept effectiveness. Muwaffaq Salti Air Base — a key US power-projection node hosting multiple fighter squadrons, including F-15s and F-35s — has sustained multiple hits; satellite imagery shows two new impact points near a northern hangar and several destroyed structures. King Hussein (H5) Air Base has recorded at least two hits; imagery shows a destroyed hangar that may have housed aircraft (presence unknown) and craters and burn marks near the runway edge, implying damage to adjacent runway areas. Faytuks says most other attacks on US facilities have largely failed and so far had limited operational impact.
