محمد باقر الحكيم

From the news reports:

Ayatollah Hakim had a long history of fighting the former Iraqi regime.

Heading the Iranian-backed Supreme Council for the Islamic Revolution in Iraq (Sciri), he had returned to Iraq after more than two decades in exile, and had cautiously supported co-operation with the US occupying forces.

Mohammad Baqir al-Hakim returned to Najaf in May to the cheers of thousands of Shiites. Speaking to the gathered Muslims, he called for a democratic Iraq, but rejected a secular government, saying it would not respect Islam. ...

The ayatollah, who did not support the war that ousted Saddam, was also a vocal critic of the U.S. presence in Iraq after the war, saying in May it was in the "best interests of everyone for the Americans to leave as quickly as possible."
