U.S. Central Command said Thursday that American forces struck Iranian military sites responsible for “unprovoked” missile, drone and boat attacks on U.S. warships in the Strait of Hormuz.

“U.S. forces intercepted unprovoked Iranian attacks and responded with self-defense strikes as U.S. Navy guided-missile destroyers transited the Strait of Hormuz to the Gulf of Oman,” CENTCOM said in a statement.

CENTCOM said Iran had targeted the USS Truxtun, the USS Rafael Peralta and the USS Mason.

“No assets were struck,” it said.
