Cairo: The US Navy acknowledged yesterday and expressed regret that an Egyptian citizen was killed when a navy-contracted ship fired warning shots at approaching motor boats in the Suez Canal.

The Global Patriot, a civilian ship under short term contract to the US Navy, entered the Suez Canal on Monday and was approached at 8pm by small motor boats that conduct informal commerce with canal shipping, prompting the onboard navy security team to fire shots after issuing verbal warnings.

"We are greatly saddened by events that apparently resulted in the accidental death," said Vice-Admiral Kevin J. Cosgriff, Commander, US 5th Fleet, said in a statement. "We ... will do our utmost to help take care of the family of the deceased," the statement said.
