US accuses Iran of conducting missile test near warships

Iranian naval vessels conducted rocket tests last week near U.S. warships and commercial traffic passing through the Strait of Hormuz, the American military said on Wednesday, causing new tension between the two nations after a landmark nuclear deal.

The vital strait, a narrow waterway between Iran and Oman that is the route for nearly a third of all oil traded by sea, is crucial for ships taking part in the war against the Islamic State group in Iraq and Syria.

While the United States has complained previously about other Iranian war games and manoeuvres there, Saturday’s incident comes after a series of weapons tests and other moves by the Islamic Republic following the nuclear deal.

Iranian media and officials did not immediately discuss the tests on Wednesday.

Cmdr. Kyle Raines, a U.S. Central Command spokesman, said in a statement that Iranian Revolutionary Guard naval vessels fired “several unguided rockets” about 1,370 meters (1,500 yards) from the USS Harry S. Truman aircraft carrier, the USS Bulkeley destroyer and a French frigate, the FS Provence. Mr. Raines said commercial sea traffic also was nearby.

He said the Iranian vessels announced over maritime radio that they’d carry out a live fire exercise only 23 minutes beforehand.

The test comes after Iran and world powers led by the U.S. agreed to a landmark nuclear deal to limit the Islamic Republic’s enrichment of uranium in exchange for lifting economic sanctions. While heralded by moderates in Iran, hard-liners have criticised the deal.

In the time since, Iran has conducted missile tests criticised by the U.S., as well as aired footage on state television of an underground missile base.
