I'm thinking Iran has reined him in. Since they were caught off guard as Reuters reports. Still, it's interesting that the Sadrists are complaining that Iraqi and US forces have exploited a truce called by the cleric last August. Hmm, sounds like America has learned the Islamofascist tricks.
MUQTADA AL-SADR, the radical Shia cleric, yesterday called on his followers to stop battling Iraqi government forces after a week of fighting in southern Iraq and Baghdad threatened to spiral out of control.
A crackdown on Shia militants in Basra has provoked an explosion of violence that risked undoing the past year's improvements in Iraq's security."Because of the religious responsibility, and to stop Iraqi blood being shed ... we call for an end to armed appearances in Basra and all other provinces," Sadr said in a statement issued in the holy Shia city of Najaf. "Anyone carrying a weapon and targeting government institutions will not be one of us."
