The U.S. Embassy in Qatar on Feb 28 issued a security alert implementing a shelter‑in‑place for all embassy personnel and urging Americans in Qatar to do the same until further notice. The advisory asked people to stay indoors in a secure location, stock essentials, avoid demonstrations, monitor local media, and enroll in STEP for updates. The alert was issued amid heightened regional tensions after reports of Israeli strikes on Iran and claims that the U.S. participated in the operation, raising fears of retaliatory action against U.S. assets in the Gulf.
