WASHINGTON, April 13 (Reuters) - U.S. President Donald Trump warned on Monday that any Iranian "fast-attack" ships that go near a U.S. maritime blockade on Iran would be eliminated.

"What we have not hit are their small number of, what they call, 'fast attack ships,' because we did not consider them much of a threat. Warning: If any of these ships come anywhere close to our BLOCKADE, they will be immediately ELIMINATED, using the same system of kill that we use against the drug dealers on boats at Sea. It is quick and brutal," Trump wrote in a post on Truth Social.
