Also, a list obtained Monday shows Saddam Hussein will be charged with a range of war crimes when he goes on trial, probably within the next two months. Iraqi officials believe offensives like Operation Lightning, along with the deposed dictator's trial, could help deflate the insurgency being waged by Saddam loyalists and Islamic extremists.
More than 840 people have died in the violence since the government was announced April 28, but the daily death toll has fallen slightly in the past three days.
Iraq's first freely elected government in more than 50 years replaced Saddam's regime, which had long suppressed Shiite and Kurdish communities in favor of minority Sunni Arabs.
The Sunni fall from power has been considered a major cause of the violence, which persisted late Sunday and early Monday. Mortar attacks and drive-by shootings killed nine Iraqis and two militants.
The latest figures released from Operation Lightning, which began May 22 in Baghdad, included at least 887 arrests and the establishment around Baghdad of 608 mobile and 194 permanent checkpoints. Also, 38 weapon stores were raided.
The operation is the biggest Iraqi-led offensive since Saddam's ouster two years ago. Before it began, authorities controlled only eight of Baghdad's 23 entrances. Now all are under government control.
