The United States launched strikes at Iran on Sunday afternoon for the first time in over a month.

The U.S. military struck Larak Island after observing Islamic Revolutionary Guard Corps forces preparing to deploy sea mines in the Strait of Hormuz, Capt. Tim Hawkins, spokesman for U.S. Central Command, told CNN. Strikes hit two rocket launchers to protect the commercial shipping lane after the military finished clearing the mines throughout the waterway last week.
