Iran's Revolutionary Guards said on Saturday that the US Navy had approached their patrol vessels in the Gulf and fired flares in what it called a provocative move.

 

"At 4 pm (1130 GMT) on Friday, the supercarrier USS Nimitz and its accompanying warship, while being monitored by the Guards' frigates, flew a helicopter near the Resalat oil and gas platform and approached the force's ships," the Guards said.

 

On Tuesday, a US Navy patrol ship fired warning shots at a Guards boat in the Gulf as it closed in on the American vessel, US officials said.
