American criminal investigators, in cooperation with their counterparts in Singapore tracked down and arrested five Singaporeans who had arranged for 6,000 American made radio frequency modules (RFMs) to be diverted to Iran. This was illegal, and was orchestrated by an Iranian citizen who is still at large. Between 2008-2010, sixteen of these RFMs were found in unexploded roadside bombs in Iraq. It was eventually found that the RFMs, and other components of the bombs, had been smuggled into Iraq from Iran. Four companies were used to deceive American export controls so that the RFMs could be redirected to Iran. Singapore is willing to extradite the five men to the United States for prosecution.
The war on Iranian arms smuggling has been intensifying in the last decade. Most countries cooperate, but not all. While Turkey has been getting cozy with Iran, the Turks still enforce international trade sanctions against Iran. But as Turkey encourages its companies to do more business with Iran, there are more opportunities to smuggle forbidden goods to assist Iranian nuclear weapons and ballistic missile projects. Iran takes advantage of this whenever possible.
