Juan Cole speculates:

There were no large rallies on Sunday, which the BBC attributes to the security forces fanning through the streets. But the security forces had fanned through the streets on Saturday, too. More likely, the reformists were regrouping after the violence and clamp down on Saturday, which left up to 13 dead. Those 13, including the unarmed young woman known as Neda Agha Sultan (1983-2009)--whose murder by a Basiji was caught on camer-- need to be mourned. The authorities cancelled memorial service for her at Nilufar Mosque. Likely it will now be held in the streets.
