"The report states there is no evidence to suggest any direct transfer of goods to ISIL [Islamic State] by the countries and companies mentioned in the [CAR] report," the State Department official said on Friday.
The official noted that the "weakest link" in the supply chain is when potential bomb-making components are sold to smaller companies in various locations around the world, making them increasingly difficult to trace.
"The report maps out the legal trade in component parts across the region and notes that producers have lawfully traded these components with regional trade and distribution companies," the official added.
The London-based research group studied the origins of over 700 components found at Daesh bomb factories, and in defective IEDs. Daesh terrorists most often use Nokia Model 105 Type RM-908 mobile telephones in the manufacture of a specific type of remote-controlled IED.
According to the report, Daesh procures a significant portion of their IED components from Turkey and Iraq.
Considerable parts of Syria and Iraq are currently controlled by Daesh, where the terror group has proclaimed a caliphate ruled by Sharia law.
