The U.S. military attacked Iran on Friday in response to an Iranian drone strike on a cargo ship in the Strait of Hormuz, further straining the fragile peace deal agreed last week between the two countries.

U.S. Central Command said aircraft struck missile and drone storage ?locations and coastal radar sites. CNN, citing an unnamed U.S. official, reported the U.S. operation had concluded. Iranian media said a projectile struck ?the ?area around a pier in Sirik in southern Iran.

Iran¡¯s Revolutionary Guard Corps on Saturday said it ?targeted U.S. ?military ?positions in ?the region, in response to the ?U.S. strike. The ?Guard did not ?provide details ?on the U.S. positions it targeted ?in ?the region.
