Report: German firms worked on Iran's nuke program

Several German companies are under investigation for alleged involvement in Iran's disputed nuclear program, a German magazine reported Saturday. Police searched the premises of eight firms as well as private homes on February 8 as part of the investigation, the Spiegel weekly said in an article released before its publication Monday. Horst Salzmann, a spokesman for federal prosecutors, declined to comment on the report. According to Spiegel, one firm from Cologne was involved in a planned delivery to Iran of equipment to detect radiation contamination on clothes and human skin.
