“U.S. Central Command forces have begun launching a series of powerful strikes against Iran to impose heavy costs for targeting and attacking commercial shipping crewed by innocent civilians in an international waterway,” CENTCOM said. “The U.S. strikes are in response to Iranian attacks on three commercial vessels that were transiting the Strait of Hormuz. Iran’s demonstrated aggression was unwarranted, dangerous, and a clear violation of the ceasefire.”

The attacks come as U.S. and Iranian officials have been negotiating about maritime traffic in the Strait of Hormuz, a key waterway through which some 20% of the world’s oil passed before the war.

Iran has argued that it has a right to charge a fee for ships passing through the strait.

The U.S. also revoked a temporary sanctions waiver that had allowed for the sale of Iranian oil on the global market on Tuesday because of Iran’s attacks.

The revoked waiver, listed on the Treasury Department’s website, said the move was effective immediately. It also said that any production, delivery or sale of Iranian oil must be wound down by July 17.

The waiver had originally allowed sales until August 21.
