Is this supposed to be a joke?

„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 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.“

Give me a break: Is the department really claiming that Iran is now sending funds and fighters to al-Qaida in Syria, including the Nusrah Front?
The claim is not only shameless, it is totally sick.
The Nusrah has publicly and more than once taken „credit“ for having targetted and killed Iranians and Shias in Syria. They have proudly burned Husseiniyas and shelled Shia mosques. They have beheaded prisoners of war after having accused them of being „Iranian dogs“ or „Shia infidels“.

No person with a single functioning brain cell does believe this garbage, unless one finds it plausible to claim that Iran is simultaneously supporting and fighting each of Syrias warring factions . Why? Because according to the US and many pro-rebel (mainly arab) sources Iran is behind Assad, Hizbullah and Iraqi Shia militias as well as their most deadly adversaries Nusra Front and ISIS.
