Here's something that's been bubbling away for a couple of days.
Hashemi Rafsanjani, the former Iranian president, was quoted by official Iranian channels yesterday as saying "a government that uses chemical bombs against its people will face hard consequences, just like Saddam, who earned eternal shame in the bombing of Halabja and suffered such a horrible fate."
The Iranian FARS news agency reported, but later amended the comments, shifting the comments away from blame.
However, reports by the Iran Pulse blog state that he made similar comments today, and a youtube videohas been uploaded of the audio. Sadly I don't have a word of farsi but the Pulse blog deconstructs it.
I probably don't need to mention that Iran is Syria's closest ally. Hassan Hassan, a very respected Middle East journalist, tweets it is "huge", although others wonder if Rafsanjani has much pull these days among the ayatollahs.
