Is Iran paying Afghan mercenaries to fight in Syria?

Syria's long-running civil war has drawn in all sorts of groups and individuals who have joined the fight on one side or another.

They say they are being paid to do so by the Iranian government with the promise of passports and jobs if they survive.
