"Al-Douri wants to spread terrorism and sectarian violence under the pretext of resistance," he said. "This will not affect the work of the government or the political process."
Al-Moussawi said al-Douri is still a wanted man, but that he doubts that al-Douri is still in Iraq because his need for extensive medical care in a well-equipped clinic would make it impossible to hide.
Also Saturday, a bomb hidden in a plastic bag blew up on a minibus, killing two passengers and wounding nine in Baghdad's commercial heart of Karrada, according to police and hospital officials. They spoke on condition of anonymity because they were not authorized to brief the media.
Deadly attacks have declined in Iraq in recent weeks, but dozens are still killed every month. March saw the lowest monthly toll for violent deaths since the 2003 U.S.-invasion.
