Pirates threatened a ship at the north end of the Strait of Hormuz in the nearest-ever attack to the waterway, which handles 20 percent of the globally traded oil, according to the International Maritime Bureau.
Armed private guards aboard the container vessel fired warning shots to deter pirates chasing the ship in three boats at the northern-most area of the Gulf of Oman, according to the bureau’s piracy reporting centre.
The pirate activity, reported on Feb. 25, “is a sign of concern if they are moving so deep into the Gulf and the Strait of Hormuz,” Cyrus Mody, a London-based manager at the centre said today by phone.
The ship identified in the report was the nearest to the Strait of Hormuz, according to a list of attacks published by the IMB over the past three years.
