Iranian Balochistan

From the Jamestown Foundation's always interesting Terrorism Monitor background on the previously mentioned conflict in the Iranian province of Sistan-Balochistan...

The escalating insurgency in Pakistan's southwestern province of Balochistan and neighboring regions receives extensive media coverage...In contrast, evidence of a simmering rebellion and escalating violence between Tehran's own ethnic Baloch minority and Iranian security forces in Iran's vast but sparsely populated southeastern province of Sistan-Balochistan is receiving far less attention. Iranian officials and other observers implicate an obscure Baloch militant organization known as Jundallah (Soldiers of God) for spearheading the uprising.

Unlike most Iranians who are Shiites, the overwhelming majority of Iran's Baloch population adheres to the Sunni branch of Islam. Despite a lack of concrete evidence, Iranian authorities and some analysts believe that Jundallah may have ties to Sunni Islamist extremists associated with al-Qaeda and the Taliban operating across the border in neighboring Pakistan and Afghanistan.

Historically, Tehran and Islamabad have collaborated in suppressing Baloch nationalism, often through brutal military crackdowns. Both countries see Baloch nationalism as a serious threat to regional stability and the territorial integrity of both states.
