No backing down:

Those who are bothered by the greatness of such a civil behavior tried to blame the fires and other destruction on the nation and supporters of reform. They are masters in engineering trouble, as they are masters in engineering elections, and in the process, they murdered a group of our countrymen. I express my condolences for these murders… They [the vigilantes] try to scare people and ignore their protests by censoring the media and showing propaganda…

A lot will hinge on Friday prayers. Karroubi is calling for a massive turnout and for people to wear black in mourning for those murdered by the regime.
