Iranian officials have detained 10 American sailors after two small U.S. naval vessels in the Gulf experienced mechanical problems en route to Bahrain from Kuwait. American diplomats said they lost contact with the crew and subsequently heard from Tehran that the Americans were safe and in their custody. Iran also assured that the “sailors will promptly be allowed to continue their journey,” potentially as early as Wednesday morning. Sec. of State John Kerry, who has reportedly formed a strong partnership with his Iranian counterpart, is on the case to ensure their safe passage.
