German police have detained four men suspected of delivering valves for a heavy-water reactor to Iran and breaking Germany's embargo on such exports imposed over Iran's disputed nuclear program.
The group includes one German and three men with dual German-Iranian nationality.
The men -- identified only as Kianzad Ka., Gholamali Ka., and Hamid Kh. -- and German national Rudolf M. were picked up early on August 15 by a force comprising 90 officers at their homes in the northern cities of Hamburg and Oldenburg and the eastern town of Weimar.
Their flats and offices were searched.
Western powers suspect that Iran wants to develop nuclear weapons.
Tehran denies the claim.
