I don't know who these detained people are and if I always take news coming from Iran with a grain of salt then why shouldn't the same principle apply to Syria? Be it Ass-ad regime mouthpiece or some rag-tag FSA member.
But I have no doubt that IRR is the main culprit on putting these people in harms way. Homs has been the epicenter of violence and bloodshed ever since March 2011. Why not put a travel ban for going to Syria and at the same time summon entire Iranian citizen in Syria back home. As usual IRR has proven itself on its failure to protect its constituents.
The video blow pops when you search the net. The poster claims it was filmed in Syria (poster's claim not mine) and on 0:06 you can clearly hear one of the operatives capturing protestors speaking in Persian and saying "Boro, Boro, Boro".

Watch it quick before IRGC cyber army removing it from U-Tube like many other coming from Syria.
