This report provides background information on Saddam-Al Qaeda links and the Iraq insurgency. U.S. officials assess AQ-I to be weakened almost to the point of outright defeat in Iraq, although they say it remains lethal and has the potential to revive in Iraq.

This report discusses the current political and social climate of Iraq, specifically in regards to the influence of the U.S. military presence over recent years.

This report provides an analysis of the current crisis, including the conditions for those displaced in Iraq and the refugee situations in Syria, Jordan, and elsewhere. It also provides information on the U.S. and international response and examines refugee resettlement options in the United States. Aspects of this crisis that may be of particular interest to the 110th Congress include a focus on an immediate response (providing humanitarian relief funding), examining resettlement policies, and developing a strategy to manage the displaced, particularly within Iraq.

This report summarizes what is currently known publicly about companies that provide personnel for security missions in Iraq and some sources of controversy surrounding them.

The various possible means for prosecuting contractors under U.S. law in civilian or military courts are detailed, followed by a discussion of possible issues for Congress, including whether protective services are inherently governmental functions. The report also summarizes pertinent legislative proposals.

This report describes recent developments in the assistance effort in post-authoritarian Iraq and key issues of potential interest to Congress.

The following casualty data was compiled by the Department of Defense (DOD), as tallied from the agency's press release. Table 1 provides statistics on fatalities during Operation Iraqi Freedom, which began on March 19, 2003, and is ongoing, as well as on the number of fatalities since May 1, 2003, plus statistics on those wounded, but not killed, since March 19, 2003. More frequent updates are available at DOD's website at [http://www.defenselink.mil/news/] under "Casualty Update." A detailed casualty summary that includes data on deaths by cause, as well as statistics on soldiers wounded in action, is available at the following DOD website: [http://siadapp.dmdc.osd.mil/personnel/CASUALTY/castop.htm].

Construction of the New Embassy Compound (NEC) in Baghdad is completed and, as of early August 2008, about 50% of post staff have moved in. Construction problems and additional requirements, including adding space at the embassy compound for General Patraeus and his staff, as requested in a mid-2007 report by State's then- Director of Management and Planning, delayed the opening by a year and raised the cost from the original $592 million estimate to about $736 million. The Department of State has a goal of having all U.S. government personnel moved in by the end of 2008.

Iraq's political system, the result of a U.S.-supported election process, continues to be riven by sectarianism and ethnic and factional infighting. The Administration asserts that the passage of key laws in 2008 will help heal remaining rifts and continue to reduce violence. Others see the schisms widening as Iraqi leaders wrangle over unresolved issues that are complicating the holding of provincial elections.

The Kurdish-inhabited region of northern Iraq is relatively peaceful and prospering economically, but the Iraqi Kurds' political autonomy and political strength in post- Saddam Iraq is causing friction with Arab leaders in Iraq, Turkey, and Iran. However, an overall reduction in violence in Iraq, coupled with continued U.S. political influence over the Kurds, is likely to prevent a destabilizing escalation of the Iraqi Kurd-Arab disputes.

A 1996 amendment to the Foreign Sovereign Immunities Act (FSIA) enables American victims of international terrorist acts supported by certain States designated by the State Department as supporters of terrorism - Cuba, Iran, North Korea, Sudan, Syria, and previously Iraq and Libya - to bring suit in U.S. courts to seek monetary damages. This report, which will be updated, provides an overview of these issues and relevant legislation (H.R. 5167).

Iran is materially assisting and influencing major Shiite Muslim factions in Iraq, most of which have ideological, political, and religious ties to Tehran. Among these factions is that of hardline anti-U.S. cleric Moqtada Al Sadr, whose Mahdi Army militia, according to some observers, serves as a proxy force for Tehran against the United States.

This report presents various governmental and non-governmental estimates of Iraqi police and security forces fatalities. The Department of Defense (DOD) regularly updates total U.S. military deaths and wounded statistics from Operation Iraqi Freedom (OIF), as reflected in CRS Report RS21578, Iraq: U.S. Casualties, and has released the monthly pattern of Iraqi security forces deaths. For information on Iraqi civilian deaths, see CRS Report RS22537, Iraqi Civilian Deaths Estimates. Because these estimates are based on varying time periods and have been created using differing methodologies, readers should exercise caution when using them and should look on them as guideposts rather than as statements of fact.

This report presents various governmental and nongovernmental estimates of Iraqi civilian dead and wounded. The Department of Defense (DOD) regularly updates total U.S. military death and wounded statistics from Operation Iraqi Freedom (OIF). However, no Iraqi or U.S. government office regularly releases publicly available statistics on Iraqi civilian deaths or civilians who have been wounded. Statistics on Iraqi civilian dead and wounded are sometimes available through alternative sources, such as nonprofit organizations, or through statements made by officials to the press. Because these estimates are based on varying time periods and have been created using differing methodologies, readers should exercise caution when using these statistics and should look on them as guideposts rather than as statements of fact.
