There were rumors last night and overnight — and let me emphasize only unsourced reports — that the Council of Experts — whose primary functions are to choose the Supreme Religious Leader in Iran, and, in theory, remove him — was being called into extraordinary session in Qom by former President Rafsanjani, who heads it. That would be a truly dramatic development, and since nothing more seems to have happened, I'd take it very cautiously.
However, this Al-Jazeera story, which interprets the whole election fiasco in terms of a Rafsanjani/Khamene'i power struggle, does not seem so far-fetched to me. Ahmadinejad beat Rafsanjani in the 2005 elections, and the bad blood has been evident. I recommend that readers at least think about this as a paradigm for understanding what's gong on,i without necessarily endorsing it.
