Iranian protesters face multiple security groups - 22 June 09

Iranians protesting against the results of the June 12 presidential vote face multiple state security groups whose aim is to lay down the law.

From the Revolutionary Guards, the most formidable force, to the Basij, a paramilitary group loyal to the government, security forces have been on the streets since the polls opened.

Now, as Al Jazeera’s Roza Ibragimova reports, the security forces say they will no longer tolerate the unrest.
