Things are really getting nasty here. After Karrubi's unbelievably blunt letter to the Supreme Leader, everything is suddenly changing. All non-fundamentalists are rallying behind Rafsanjani. Many are talking about a possible coup by Sepah and Basij after Friday's second round results.

It's also rumoured ("now confirmed":http://www.irna.ir/en/news/view/menu-234/0506200312115058.htm ) that Eqbal and Aftab, pro-reform newspapers, were seized in the printing house last night after they published full text of the letter.

Karrubi for the first time has publically challenged the Supreme Leader and has accused his son of paving the way for an unexpectedly high vote for Ahmadinejad.

As for my own self, I've been advised to stay in Tehran for a couple of more days. But I have to attend a conference in London on Wednesday and if I can't get there by then, it'll be a huge risk staying in Iran.
