US Central Command (CENTCOM) announced Friday that American forces conducted military strikes on Iran in a “powerful response” to an Iranian drone attack on a commercial ship transiting the Strait of Hormuz.

Iranian drone storage facilities and coastal radar sites were hit by US warplanes in retaliation for the Thursday attack on the M/V Ever Lovely, a Singapore-flagged cargo ship.

“The unwarranted aggression against commercial shipping by Iranian forces clearly violated the ceasefire,” read a statement released by CENTCOM. “Furthermore, Iran’s dangerous behavior undermined freedom of navigation as commerce increasingly flows through the vital international trade corridor.”

“CENTCOM forces continue to provide safe passage coordination and support to commercial vessels transiting the strait,” the statement continued. “The U.S. military remains present and vigilant to ensure all aspects of the agreement with Iran are adhered to, obeyed, and in full force and effect.”
