The United States carried out a 13th consecutive night of airstrikes on Iran early Friday, targeting military infrastructure linked to Tehran's operations in the Strait of Hormuz, while air raid sirens sounded in Bahrain and the widening conflict threatened to further disrupt global energy supplies and key shipping routes.

The latest wave of strikes lasted just over two hours, ending around 4:30 a.m. local time, according to U.S. Central Command (CENTCOM).

The military said it struck Iranian military command centers, drone storage facilities, communications networks, coastal surveillance sites and maritime assets in an effort to weaken Iran's ability to threaten commercial shipping in the Gulf.

CENTCOM said the operation was intended to further reduce the danger posed to civilian vessels traveling through the Strait of Hormuz, one of the world's most important energy corridors, while insisting that the waterway remains open under U.S. military protection despite recent Iranian attacks.

Iranian media reported explosions across several parts of the country, including areas near Ahvaz, Andimeshk and Omidiyeh in the southwestern province of Khuzestan.
