According to the German Federal Customs Service's investigative unit (ZKA), Iran has sought to buy components for its nuclear program on the German market over the past few months.  Using front companies to conceal its activities, Iran has successfully purchased sanctioned goods in some cases.  ZKA chief Norbert Drude reported that over two-third of the investigations undertaken by Customs in 2012 and 2013 involved Iran.  This story was first reported by the German daily Der Tagesspiegel on November 16.
