The US Navy supply ship USNS Rappahannock in the South China Sea on March 21, 2012
The US Navy Fifth Fleet says the sailors on the ship that launched a deadly attack in the Persian Gulf had warned the fishermen on the targeted boat before they opened fire.
The Bahrain-based fleet issued a statement on Monday saying that the USNS Rappahannock only attacked a small motor boat near the Dubai port of Jebel Ali, killing one and injuring three Indian fishermen, after they "ignored the warnings and came too close," Xinhua reported.
The statement added that the US ship used a series of non-lethal, preplanned responses to warn the vessel's operators to turn away from their "deliberate" approach before resorting to lethal force.
Jebel Ali port, one of the largest ports in the Middle East, is the most frequently visited port by ships of the US Navy outside the United States.
Washington recently expanded its military presence in the Persian Gulf, sending an unspecified number of F-22 stealth fighters and warships to the region.
