The US Navy said it responded and prevented the seizures. "The Iranian navy did make attempts to seize commercial tankers lawfully transiting international waters," Cmdr. Tim Hawkins, spokesman for the U.S. Navy's Fifth Fleet, confirmed in a statement. "The U.S. Navy responded immediately and prevented those seizures."

It was only the second tanker which was fired upon during the incident, leaving no casualties or major damage. 

The Associated Press described the tanker which was fired upon as US managed, though Bahamas-flagged and Greek-owned:

Ambrey, a maritime intelligence service, said the tanker that was fired upon was a Bahamas-flagged, Greek-owned, U.S. managed crude oil tanker transiting from the United Arab Emirates to Singapore. It said the firing of shots happened 28 nautical miles northeast of Muscat, the capital of Oman.
