Four ships of the Islamic Revolution Guards Corps (IRGC) on Thursday threatened US destroyers in the area of the Strait of Hormuz in Iran, Reuters reported, citing its own sources in the Ministry of Defense.

The official, who asked to remain anonymous, said that the Iranian ship sailed 300 m to the armed naval destroyer Nitze of US Forces, and called the incident "a dangerous and unprofessional."

“Iranian destroyer ships chased at full speed, approaching Nitze at a dangerous distance, ignoring the warnings,” said the US official.

During the incident on Tuesday, the crew of the US destroyer Nitze called on Iranian ships 12 times, but received no response. Also, the Americans fired 10 flares in the direction of the Iranian ships.

“The American ship had to change course to distance itself from the Iranian vessels,” the official said, adding that the incident could lead to a diplomatic protest, but the US does not have diplomatic relations with Iran.

Iran released 10 detained sailors of the US Navy in January this year after they mistakenly entered the Iran's territorial waters in the Persian Gulf. The Islamic Revolution Guards Corps said they interrogated the American sailors and released them after 15 hours of detention.
