The U.S. military launched a series of strikes against Iranian targets early Wednesday after three merchant ships were struck in the waters off Oman.

In a statement posted to social media, U.S. Central Command said American forces launched the strikes “to impose heavy costs for targeting and attacking commercial shipping crewed by innocent civilians in an international waterway.”

“Iran’s demonstrated aggression was unwarranted, dangerous, and a clear violation of the ceasefire,” the statement said.

More to come.
