US Navy ship fires at boat in Gulf The US Navy said on Monday a security team aboard one of its ships fired on a small boat after it disregarded warnings and raced towards the vessel near the Dubai port of Jebel Ali, according to various reports. Lieutenant Greg Raelson, a spokesman for the navy's Bahrain-based fifth fleet, says sailors aboard the USNS Rappahannock, an oil supply ship, issued a series of warnings before resorting to lethal force using a .50-calibre machine gun, the Associated Press reported. Sky News quoted a US consular official in Dubai as saying that one person was killed and three others injured in the incident. The official gave no other details, but it appeared the boat could have been mistaken as a threat in Gulf waters not far from Iran's maritime boundaries. The boat was apparently a civilian vessel. A US navy official told ABC news the incident had "nothing to do with Iran," despite heightened tensions in the region owing to threats by Iranian politicians to close the Gulf. More follows . . .
