"With only a few days since a provocative move in the northern end of the Persian Gulf in which the US Navy ships fired warning shots at an Iranian vessel, the American warships have once again taken the same action in the middle of the Persian Gulf,” the IRGC said in a statement on Saturday.
The statement was referring to an earlier similar move by a US Navy ship on July 25.
"At 4:00 PM Friday, July 28, US Nimitz-class aircraft carrier accompanied by its warship, while under surveillance by IRGC missile boats, began flying a helicopter over the ‘Resalat' gas-oil field and approaching IRGC vessels,” the statement added.
The statement notes IRGC Navy’s vigilance, adding "the US warships in a provocative and unprofessional move began firing warning shots at the Iranian vessels, to which the IRGC Navy’s ships paid no attention and continued with their mission."
The US aircraft carrier and its accompanying warship later left the area, the statement added.
