A resistence quite different from the post-election peaceful demonstrations in Iranian cities has been evident in Iranian Baluchistan over the past five years and more. The Jundallah "Soldiers of God" Sunni group, led by Baluchi Abdolmalek Rigi, of the Rigi tribe of the northern Sarhad region, has repeatedly attacked Iranian security services. Two days ago, on 18 October 2009, the Jundallah insurgency struck with a suicide bomber at a meeting of Iranian security officials and tribal leaders. Six senior revolutionary Guard commanders, including the Deputy Head of Revolutionary Guard Ground Forces, and the RG Commander for Sistan & Baluchistan Province, were killed. The Jundallah has claimed responsibility.
As the National Post (20 October 09: A9) puts it, "Tehran said Abdolmalek Rigi, a Sunni rebel leader, had claimed responsibility for the attack at a gymnasium in Pisheen. His Jundallah (Soldiers of God) group has been waging war against the Shiite rule of Iran for years. ...
"The Baluchis, who are mostly Sunni, are one of many ethnic and religious minorities who have complained of discrimination in Iran, a predominantly Shiite and ethnically Persian nation."
Iran of course blames the U.S., Britain, and Pakistan for supporting this insurgency. There is no evidence of reflection about the Shia Islamic Republic treatment of the Sunni minority.
I have information direct from Baluchistan, but second-hand, that the Sunni Baluch are extremely irritated with the Shia chauvinism that is constantly flaunted by the government and its agents and institutions, and by the disadvantages imposed on Baluch because they are Sunni, and thus deemed inherently disloyal to the Shia I.
