TEHRAN, July 12 (Xinhua) -- Iran's Islamic Revolution Guard Corps (IRGC) said it targeted U.S. bases in Jordan, Qatar and Oman on Sunday in retaliation for U.S. attacks against southern Iranian provinces earlier in the day.

In statements published on its official news outlet Sepah News, the IRGC said the U.S. Army had carried out airstrikes against several coastal military bases and communications towers along Iran's southern coasts.

In the first phase of its retaliatory operations, the IRGC said its forces hit "important" U.S. infrastructure and facilities at the Prince Hassan Air Base in Jordan, destroying the base's command and control center and the hangar for MQ-9 Reaper drones.

In the second phase of its strikes, the IRGC targeted and stopped a "violating" vessel in the Strait of Hormuz, and hit the U.S. Al Udeid Air Base in Qatar, devastating its command as well as fighter aircraft overhaul and maintenance centers.

In the third phase, it noted, the logistical support centers and refueling platforms of U.S. aircraft carriers in the Omani port city of Duqm were targeted and demolished in a "heavy and surprise" attack.

The Iranian Army also targeted drone attacks early Sunday on what it described as "terrorist" U.S. Army bases and centers in Kuwait and Bahrain in response to the U.S. "aggressions" earlier in the day.

It added that in Kuwait, a Patriot air defense system, an ammunition depot and a radar site belonging to the U.S. Army were hit by Iranian kamikaze drones, while in Bahrain, the U.S. Army's communications system and a radar site were targeted.

The IRGC warned of more severe responses if the United States repeats its attacks against Iran.

The IRGC's Navy stressed that given the insecurity in the Strait of Hormuz caused by "foreigners' illegal interference," the strait will remain closed until further notice, and that until the United States stops its interventions in the region, no vessel would be allowed passage.
