An al-Qaeda network based in Iran is helping transport fighters and money to Syria via Turkey, the US Treasury Department has said.

“Today the U.S. Department of the Treasury announced the designation of a key Iran-based al-Qa’ida facilitator who supports al-Qa’ida’s vital facilitation network in Iran, that operates there with the knowledge of Iranian authorities,” the Treasury Department wrote in a statement on its website on Thursday that announced actions “targeting a diverse set of entities and individuals located around the world for evading U.S. sanctions against Iran, aiding Iranian nuclear and missile proliferation, and supporting terrorism.”

It also said, “The network also uses Iran as a transit point for moving funding and foreign fighters through Turkey to support al-Qa’ida-affiliated elements in Syria, including the al-Nusrah Front.”
