The US military denied the Strait of Hormuz had been closed on Saturday, saying the critical waterway remained open and that US forces were monitoring the situation to ensure that continued.
"Iran does not control the Strait of Hormuz," US Central Command spokesperson Navy Captain Tim Hawkins told Reuters.
"Traffic continues to flow, and US forces are monitoring the situation to ensure this remains the case."
