TEHRAN, April 2 (Xinhua) - Iran's Islamic Revolution Guards Corps (IRGC) said Thursday it has targeted and destroyed Amazon's cloud computing operation center in Bahrain in its first action against U.S. and Israeli "espionage" firms in the region in retaliation for the "assassinations" of Iranians.

In a statement on its official news outlet Sepah News, the IRGC said it had issued a warning in the past concerning possible attacks on such firms given more U.S. and Israeli strikes, and that the attack in Bahrain was in response to U.S. and Israeli disregard of the warning by continuing to strike Iranians on Wednesday.

It vowed to "punish" more firms as such "more severely" if U.S. and Israeli attacks on Iranians continue.

It said it also struck seven U.S. and Israeli airbases, two U.S. steel companies in Abu Dhabi, an aluminum plant in Bahrain, factories operated by Israeli arms firm Rafael, and a hideout of U.S. troops near Bahrain's capital Manama, causing casualties among U.S. forces.

Israel and the United States launched joint attacks on Tehran and several other Iranian cities on Feb. 28, killing Iran's then Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded with waves of missile and drone strikes targeting Israel and U.S. assets in the Middle East.
