>> Bayoumy says the increasing missile shipments could be linked to recent targeting of American ships off the coast of Yemen.>> US officials do say that what they are sure about is that the missiles, which targeted the US Navy warship did come from what is Houthi-controlled territory. There is now a lot of analysis as to whether they are Iranian origin or have components from Iran.
