Ali Shamkhani, an adviser to Iran’s Supreme Leader Ali Khamenei, warned on Wednesday that Iran would respond to any attack, referring to a past Iranian missile attack on the US Al Udeid base in Qatar.

"The President of America, who repeatedly mentions the futile aggression against Iran's nuclear centers, would do better to also refer to the plowing of the American Al Udeid base by Iranian missiles," Shamkhani wrote on X.

Al Udeid is the largest US military base in the Middle East, hosting around 10,000 troops. Iran fired missiles toward the base in June after US strikes on Iranian nuclear facilities, causing limited damage.

Reuters reported earlier on Wednesday that the United States was withdrawing some personnel from major military bases in the Middle East as a precaution amid heightened regional tensions.
