Trump instructs U.S. Navy to destroy Iranian gunboats "if they harass our ships at sea"

President Donald Trump said on Wednesday he had instructed the U.S. Navy to fire on any Iranian ships that harass it at sea, a week after 11 vessels from Iran's Islamic Revolutionary Guard Corps Navy (IRGCN) came dangerously close to U.S. ships in the Gulf.

"I have instructed the United States Navy to shoot down and destroy any and all Iranian gunboats if they harass our ships at sea," Trump wrote in a tweet, hours after Iran's Revolutionary Guards Corps said it had launched the country's first military satellite into orbit.
