Hundreds of employees of the Tehran Metro Co., which is run by Hashemi Rafsanjani's son, staged a protest in downtown Tehran on Sunday. They're demanding higher wages, renewal of their contracts with the mother company and more labor rights.

I've to say that if you see pictures of Khomeini or other mullahs in their hands, it doesn't mean any thing. I guess they are carrying it to prevent the Islamic thugs to attack them and ruin their peaceful protest.
