WASHINGTON: (DNA) – Iranian Deputy Foreign Minister Abbas Araqchi denied on Friday that Iran had lost a drone in the Strait of Hormuz after the United States said that a US Navy ship had “destroyed” an Iranian drone.

“We have not lost any drone in the Strait of Hormuz nor anywhere else. I am worried that USS Boxer has shot down their own UAS [Unmanned Aerial System] by mistake!,” Araqchi said on Twitter, referring to a US warship in the strategic waterway.

US President Donald Trump said on Thursday that the drone had flown to within 1,000 yards (metres) of the USS Boxer and had ignored “multiple calls to stand down” in the latest episode to stir tensions in the Gulf.

The USS Boxer “took defensive action” against the Iranian drone as it was “threatening the safety of the ship and the ship’s crew,” Trump announced at the White House.

“The drone was immediately destroyed,” he added.

The downing of the drone comes at a time of mounting tensions in the Gulf region between the US and Iran which has been slapped with a raft of sanctions by the Trump administration.

“This is the latest of many provocative and hostile actions by Iran, against vessels operating in international waters,” said Trump.

“The United States reserves the right to defend our personnel, our facilities, and interests and calls upon all nations to condemn Iran’s attempts to disrupt freedom of navigation and global commerce.

“I also call on other nations to protect their ships as they go through the Strait and to work with us in the future.”
