Iran Warns Vessels Violating Hormuz Transit Rules of Fines, Detention

Iran's maritime authority has blacklisted 45 tankers and warned foreign vessels of fines and potential detention for violating transit rules through the Strait of Hormuz, the world's most critical oil chokepoint. The warning comes as the U.S. Treasury prepares sweeping sanctions on Iran's economy, and Tehran has threatened to halt Persian Gulf oil exports in response to intensifying economic pressure. The dispute raises concerns about global energy supplies and shipping in one of the world's busiest waterways.
