Iran has a terrorist problem, too.

I thought this was an interesting post at the Mother Jones blog speculating that Saturday's mosque blast in the southern Iranian city of Shiraz might represent some Sunni/Al Qaeda blowback from Iran's operations supporting the Shia militias in Iraq. (although I'm not sure I fully agree with the blanket Al Qaeda tie in.)

Iran has several groups targeting them, Kurdish groups and the MEK working out of northern and central Iraq as well as the Baluch terrorists Jundallah in the south (Sunni, Wahabi, but not directly Al Qaeda) which ABC reported a year ago had US ties and support.

I just thought it was interesting and never gets talked about.
