The U.S. Treasury designated General Gholamreza Baghbani, who runs the Revolutionary Guards' Quds Force office in Zahedan, near the Afghan border, as a narcotics "kingpin."
Baghbani is accused of aiding Afghan drug runners in moving opiates into and through Iran, as well helping send weapons to the Taliban.
The Treasury said in a statement that "U.S. persons are prohibited from conducting financial or commercial transactions with General Baghbani, and any assets he may have under U.S. jurisdiction are frozen."
