The Obama administration on Wednesday hit three senior Al Qaeda figures based in Iran with sanctions, accusing them of helping transfer money and fighters from South Asia to the Middle East.

The Treasury Department announced Wednesday that it had identified Saudi national Faisal Jassim Mohammed al-Amri al-Khalidi, Egyptian national Yisra Muhammad Ibrahim Bayumi and Algerian national Abu Bakr Muhammad Muhammad Ghumayn as “specially designated global terrorists.”

The punishments freeze any assets the trio may have in U.S. jurisdictions and bars Americans from doing business with them.

According to the feds, al-Khalidi is an Al Qaeda military commission chief and former battalion commander who had ties with the Pakistani Taliba. They say Bayumi is the group’s liaison with Iranian authorities and Ghumayn is in charge of Al Qaeda fighters living in Iran.
