"We have absolutely no indication whatsoever the Iranian ships ever docked in Syrian ports," said Pentagon spokesman George Little, adding that the United States believed the ships in fact "did not dock in Syria."
With Shi'te-led Iran already at odds with the United States, Europe and Israel over its nuclear program, the deployment of the warships could have fanned concerns that the Syria crisis could boil over into a regional conflict if it not resolved soon.
Instead, Little said there appeared to be nothing "particularly noteworthy" about the latest deployment of the warships.
"It seems this was a relatively routine transit through the (Suez) Canal and now, apparently, back," he said.
