UPDATE: New attack on tanker in Strait of Hormuz escalates tensions as Iran mourns Khamenei and warns all vessels must use approved routes or face decisive action.
A tanker traveling through the Strait of Hormuz caught fire early Tuesday morning after being struck by a projectile, according to the British military. The attack marks the latest assault on vessels moving through the strategic waterway, through which a fifth of all oil and natural gas once passed in peacetime. Iranian state television said the liquefied natural gas tanker came under attack after ignoring warnings, though Tehran did not directly claim responsibility for the strike.
The attack comes as Iran mourns Supreme Leader Ayatollah Ali Khamenei, who was killed at the beginning of the February 28 war. Iran's joint military command warned last Thursday that all oil tankers must use its approved routes through the strait, stating that interference by U.S. forces "will be met with a rapid and decisive reaction." However, the U.S. Navy's Joint Maritime Information Center told shippers Monday that the route around Oman "has been expanded and remains available for all traffic."
The strike highlights ongoing disputes over control of the waterway. Iran and the United States agreed as part of an interim deal to allow ships to pass without charges for 60 days, but Tehran insists it must control vessel routes and later charge fees for passage. President Trump warned Iran Monday that they need to "make a deal or we're going to finish the job," adding he'd rather negotiate because "I don't want to affect 91 million people." The U.S. and Gulf Arab states say they won't agree to Iran charging for passage through the strait.
