Iran warns of 'crushing' retaliation if U.S. repeats attacks

If the U.S. repeats its aggression against Iran, it will "receive more crushing and regrettable responses that will serve as a lesson for history," Commander-in-Chief of the Islamic Revolution Guards Corps, IRGC, Brigadier General Mohammad Pakpour, was quoted by Mehr News Agency as saying.

IRGC stated on Monday night that the message of their decisive counterattacks against earlier U.S. missile bombings is clear and unequivocal for the White House and its allies.

"Accordingly, we would like to remind (everyone) that in this national defense, the U.S.' mobile military bases and targets in the region are not a point of strength, but rather a major weakness and Achilles' heel of this war-mongering regime."

The Supreme National Security of Iran said that in its operation against a U.S. base in Qatar, the country launched an equal number of missiles as the bombs used in Washington's Sunday attacks on Iranian nuclear facilities.

In statement issued on Monday night, the SNSC described how the IRGC targeted the United States' Al-Udeid air base in Qatar in an operation codenamed "Promise of Victory".

"In response to the United States' aggressive and brazen act against Iran's nuclear places and facilities, our powerful Armed Forces destroyed the American forces' air base in Al-Udeid of Qatar a few hours ago," it said in a statement on Monday night quoted by Iran's Tasnim News Agency.

"The number of missiles used in this successful operation was equal to the number of bombs the U.S. used in the attack on Iran's nuclear facilities, and the base targeted in the attack by Iran's powerful forces is far from urban facilities and residential areas in Qatar," the SNSC added.

Iran stressed that its missile attack "did not pose any threat to our friendly and brotherly country, Qatar, and its noble people, and the Islamic Republic of Iran remains committed to maintaining and continuing warm and historic relations with Qatar."

The Iranian missile strikes were in direct response to the U.S. attacks on three Iranian nuclear sites a day earlier.
