Death of 'Iraq's Khomeini' leaves power gap

Ayatollah Mohammed Baqir al-Hakim had just delivered a sermon calling for Iraqi unity and Friday prayers were under way at Iraq’s holiest Shiite shrine when a car bomb exploded.

Al-Hakim, 64, was killed just months after the fall of Saddam Hussein enabled him to return to his native country after more than two decades in exile in Iran.
