Gunners aboard a U.S. Navy refueling ship opened fire on a small boat racing toward them in broad daylight Monday near the Gulf city of Dubai, killing one person and injuring three. Navy spokesman Lt. Greg Raelson said a security team aboard the USNS Rappahannock issued a series of warnings before resorting to lethal force about 10 miles off the coast of Dubai’s Jebel Ali port — close to Iranian waters.
