U.S. carries out new strikes against Iranian military facility, official says

The U.S. military carried out another round of strikes on Iran, a U.S. official confirmed to CBS News on Wednesday, another challenge to a shaky ceasefire between the two countries.

The official described the strikes as defensive, targeting a military site that threatened American forces and commercial traffic. The official said the U.S.-Iran ceasefire is still considered to be holding.

Reuters was first to report on the new strikes.
