Iran shot down a U.S. drone which it claimed had breached Iranian airspace. IRGC Commander Hossein Salami declared that "borders are our red line, and any enemy violating these borders will not go back". The U.S. military asserted that the aircraft had been "operating in international airspace over the Strait of Hormuz", and contended that "this was an unprovoked attack". President Trump suggested that “they made a mistake, and I’m not just talking the country made a mistake. I think that someone under the command of that country made a big mistake…I find it hard to believe it was intentional”. He went on to state that “this is a very fly in the ointment, what happened shooting down the drone. And this country will not stand for it, that I can tell you”.
