Two US Navy warships armed with Tomahawk cruise missiles have entered the Persian Gulf with a carrier strike group on stand-by off the coast of Oman, as Washington keeps accusing Tehran of planning to attack "American interests." Guided missile destroyers USS Gonzalez (DDG-66) and USS McFaul (DDG-74) transited the Strait of Hormuz on Thursday afternoon, the US Naval Institute (USNI) reported. Their sailing proceeded "without challenge" or "harassment" from the Islamic Revolutionary Guard Corps, despite boiling hot tensions between Tehran and Washington, the publication's defense sources noted. The two destroyers are now in close proximity to other American warships in the region sent by Washington earlier this month to tackle what the US called "heightened Iranian readiness to conduct offensive operations against US forces and our interests." No evidence has yet been offered to back up those claims.
