Federal prosecutors said Friday they have charged two Germans with spying and violating German export laws in a case media reports have said involves delivering weapons technology to Iran. Prosecutors identified the men only as Volker St., 46, head of an unidentified company based in the eastern state of Thuringia and specializing in vibration technology, and Peter Paul K., 65, responsible for developing and exporting the company's "vibration test systems."The pair are charged with violating German export laws by selling a vibration test system for 200,000 euros to a procurement agency employed by an unidentified foreign military intelligence service, prosecutors said in a statement. German media have reported the technology was intended for Iran, to be used in its Shahab, or Shooting Star, medium-range missile program that can carry a nuclear warhead and reach Israel and various U.S. military bases in the region. Frauke Scheuten, a spokeswoman for prosecutors in Karlsruhe, refused Friday to comment further on the charges, which were filed on January 23. According to prosecutors, the equipment was sent in January 2002 to a company in a third country, who delivered it to those who had ordered it.
