Iran fired at least two missiles at commercial ships transiting the Strait of Hormuz on Monday night. A U.S. official confirmed that the missiles struck two commercial ships.
The two vessels suffered significant damage, although there were no reported casualties.
These attacks test a late-June deal with the U.S. to halt attacks as the two sides work toward a peace agreement. Iranian officials have not provided an immediate comment on the reported attacks.
The incidents could complicate ongoing negotiations to end the U.S. war with Iran.
