U.S. Navy Vessel Fires Warning Shots at Iranian Ship in Persian Gulf | 26 July 2017 | A U.S. Navy patrol boat fired warning shots Tuesday near an Iranian vessel that American sailors said came dangerously close to them during a tense encounter in the Persian Gulf, the first such incident to happen under President Donald Trump. Iran's Revolutionary Guard later blamed the American ship for provoking the situation. The encounter involving the USS Thunderbolt, a Cyclone-class patrol ship based in Bahrain as part of the U.S. Navy's 5th Fleet, is the latest confrontation between Iranian vessels and American warships...Iranian forces view the American presence in the Gulf as a provocation by itself.
