Iran warships escort cargo vessel toward Yemen
Two Iranian warships have joined a cargo ship that Tehran says is carrying supplies to Yemen.
US Army Col. Steve Warren says the ships linked up overnight Monday, setting up a possible conflict as the US insists the supplies go to Djibouti, where the United Nations is coordinating humanitarian aid for Yemen. A US official says there's no evidence the Iranian ship is carrying lethal or military aid. The official spoke on condition of anonymity because the official was not authorized to discuss the matter publicly.
