June 10 (UPI) -- Iran said it launched strikes against U.S. military bases in neighboring countries in and around the Persian Gulf early Wednesday in retaliation for American "aggression" after U.S. forces conducted strikes on targets in southern Iran.

Khatam al-Anbiya Central Headquarters, Iran's central command, said in a statement published by the state-run Islamic Republic News Agency that the "brave Army of the Islamic Republic and the Islamic Revolutionary Guard Corps" carried out a "powerful assault" on U.S. military assets in the region.

"The criminal U.S. military should know that if aggression against the Islamic Republic of Iran is repeated, even more severe and widespread attacks will be carried out against the designated target bank in the region, it added.

The statement was accompanied by a photo showing six ground-launched ballistic missiles blasting off from an undisclosed desert location but it was unclear if it was of Wednesday's strikes as the image was undated and uncredited.
