The US Nimitz-class aircraft carrier and another warship fired warning shots at Iranian vessels in the middle of the Persian Gulf on Friday, according to Islamic Revolutionary Guard Corps (IRGC), as cited by local media.
The U.S. Navy said Saturday that a naval helicopter noticed a group of Islamic Revolutionary Guard ships heading toward the USS Nimitz's strike group "at a high rate of speed".
The incident came after a US Navy patrol boat fired warning shots on Tuesday near an Iranian vessel that American sailors said came dangerously close to them during a tense encounter.
On Tuesday, a US Navy ship fired warning shots at an armed Iranian patrol boat in the northern end of the Persian Gulf, according to two US defense officials.
"The Americans made a provocative and unprofessional move by issuing a warning and shooting flares at vessels", the statement said. The aircraft carrier was accompanied by cruiser.
A United States official, speaking on the condition of anonymity, said the Iranian boat was armed but its weapons were unmanned.
A US defense official told NBC News that three Iranian boats were involved and at least one of them had sped toward the USS Princeton, which was part of the Nimitz's carrier strike group.
Also Saturday, Iran's parliamentary committee on national security and foreign policy held an urgent meeting to review its response to a package of sanctions approved by the US Senate and sent to Donald Trump to be signed into law.
"The Persian Gulf security relates to the countries of the region which have common interests, and not to the US".
"It is a breach of the deal in articles 26, 28 and 29", said Araghchi. The measure would also apply sanctions to the Revolutionary Guard and enforce an arms embargo.
