President Donald Trump accuses Iran of violating the cease-fire after at least four One Way Attack Drones targeted ships in the Strait of Hormuz and says US forces shot down three of the drones while one hit a cargo ship off Oman.The British military confirms a vessel off Oman was struck and reports allied units are monitoring the area as the damaged ship continued its voyage despite upper-deck damage.The White House says the attack breaches a memorandum negotiated in Switzerland that Vice President JD Vance helped broker with Iranian representatives and mediators from Pakistan and Qatar and that the document requires free transit through the strait.Naval officers and diplomats warn the strike complicates efforts to reopen the strait, raises the risk of escalation and forces shipping companies and insurers to reassess routes while the US weighs military and diplomatic responses.
