Masoud at the Newest Deal sets the scene for the Green movement today:
The question remains, will the regime's response to the protests be similar to what was witnessed on Qods Day, where massive turnout caught the regime off-guard, or will it instead be in the vein of 13 Aban, where gatherings were systematically and ruthlessly broken up by Basij and Revolutionary Guard agents? If events leading up to today's demonstrations are any indicator, the regime is undoubtedly preparing for a clash with protesters: student leaders and activists have been arrested en masse, internet access has been all but disconnected as of yesterday, and most recently the mothers of 21 victims of killed by the regime in post-election violence have been arrested for congregating in Tehran's Leleh Park. (The mother of Neda-Agha Soltan, who recently and explicitly blamed the regime for her daughter's death, is rumored to be among those arrested).
