This astonishing scene - perhaps the most astonishing scene we've yet seen from today's remarkable events - seems to show a bunch of baseej pinned and cornered against a wall by protestors, in some kind of grinding and at this point non-violent impasse.
Here's a translation:
People ask them 'why do you do this to your people?' and the riot guards ask for forgiveness, 'Bebakhshid' they can be heard to say.
'You are Yazid's - the Khalif against whom the Ashura uprising took place -forces', the woman shouts at them. One of the protesters then reassures them that they will not be beaten up, all they have to do is say Khamenei is a bastard. The woman can then be heard saying 'All you can do is kill your people is it?' and again they plead saying 'Please We are not killers'.
A reader adds:
What he leaves out is that the young woman who is heard towards the end yells "Are you only brave on your motorbike, you piece of shit?!" before apparently kicking him as a man tells her to stop.
