1320 GMT: A Clash with the Dervishes. A curious story from Friday....
Basiji militia reportedly opened fire with tear gas and bullets on members of the Gonabadi Dervishes, a sect of Sufi Islam. The shooting lasted almost an hour until a Special Forces Unit, despatched from Shiraz in southern Iran, ended the clashes.
The Basiji also allegedly raided houses and set stores on fire. The trouble reportedly began when a young Muslim seminary student distributed pamphlets and CDs amongst Basiji forces and chanted “Death to American Dervishes”, inciting them to attack.
A number of injuries amongst Basiji and dervishes were claimed.

1255 GMT:CNN has picked up on Saturday's story that the Iranian military is claiming it has killed 30 members of the Kurdish insurgency PJAK in a new offensive on the Iraq border.
There are further significant developments. The separatist Kurdistan Workers’ Party (PKK), which has waged a long battled against Turkish forces, said on Saturday that it will aid PJAK, based in camps in northern Iraq.
“From now on we will fight on the side of the fighters of PJAK (Party of Free Life of Kurdistan) against the Iranian attacks, that are trying to enter the Kurdistan region of Iraq, especially in the Qandil area,” PKK spokesman Dozdar Hammo said. “We are a force to protect the people of Kurdistan. We see it is our duty to protect the achievements of the people of Kurdistan in any part....We see that the goal of Iran is eliminating the Kurdish people, and not the PJAK party, and these are the reasons that led us to take this decision.
A local official from the Iran-Iraq border area said that Iranian forces attempted to take control from PJAK of a mountain near Sardasht in Iran on Friday. They were not able to do so, and then began shelling several areas of Iraq Kurdistan, with the attack continuing through Saturday.
A shepherd was reportedly killed by Iranian shelling earlier on Saturday, while Iranian State broadcaster IRNA says a member of the Iranian security forces in Sardasht has been slain.

There is something different about these protests. The demonstrations that started after the elections in 2009 were driven by a desire for real democracy; freedom of speech, expression, religion, and assembly; and a general discontent at the state of life in Iran, especially among the youth.
This spate of dissent and anger has been propelled by a specific environmental issue that is growing in its economic impact. As Lake Urmia dries, the ecological disaster is disrupting trade and industries that relied on the lake, and it is affecting the health of the residents. These issues are more urgent, more immediate, and as a result, the protest over them may catch on faster and spread further.
In Arab Spring, the catalysts for unrest were economic, though the goals of the protesters always include democratic ends. These protests are coming from a similar place, as government policies result in real economic hardship in the cities and towns affected by the lake. Economic drivers, plus political drivers, led to the fall of three governments. This is ultimately the largest threat to the Iranian regime.
