Iraq Body Count has an unverified database with the number of Iraqis who have been killed by military intervention since the invasion based on media reports and morgue data.

A survey by researchers in the United States and Iraq published in October 2006 said more than 600,000 people had died between 2003 and 2006.

Another survey, published by the U.N. World Health Organisation in January 2008, estimated around 150,000 deaths during the same period.

The BBC is good for news, and the U.N. news service IRIN regularly gives fantastic coverage of human angles to the chaos in Iraq.

The International Crisis Group website has in-depth analysis. Chatham House is another think tank with good analysis, including a 2007 report detailing the multiple conflicts and insurgencies in Iraq.

For information on Iraqis who have been displaced or are leaving the country go to the U.N. refugee agency's website. There are also figures for those who left during Saddam Hussein's rule and are returning.

A disproportionately high number of those fleeing are from Iraq's religious and ethnic minorities. This very readable 2007 report by Minority Rights Group International Assimilation, Exodus, Eradication; Iraq's minority communities since 2003 describes how some groups could be wiped out from the homeland they've lived in for centuries.

Forced Migration Review, published by Oxford University's Refugee Studies Centre, dedicated an entire issue to Iraq's displacement crisis in June 2007, with detailed articles on conditions in Syria and Jordan, women's rights, trapped Palestinians, domestic violence and child labour, among many other angles.

The U.N. Assistance Mission for Iraq, a portal for U.N. agencies working in the country, is relatively useful, especially the monthly updates and good maps. The Geneva-based International Committee of the Red Cross (ICRC) is another source of up-to-date humanitarian information.

Human rights organisations Amnesty International and Human Rights Watch are monitoring the situation in Iraq pretty closely.

To find out what Iraq's biggest donor is doing go to the U.S. Agency for International Development. For details of British aid go to the Department for International Development.

The U.S.-led Multi-National Force website carries videos of military press briefings, photos and updates on reconstruction projects.

An interesting place to get one perspective on life in Iraq is Baghdad Burning, a blog by an articulate young woman in Baghdad. Although she stopped writing when she fled to Syria in 2007, it's an often humorous account of what it's like to live in a city under siege. Global Voices rounds up other blogs from Iraq.

Several organisations have issued reports on the humanitarian situation five years after the invasion. These include a report by the ICRC called Iraq: No let-up in the humanitarian crisis and another published by the London-based think tank Overseas Development Institute called Humanitarian action in Iraq: putting the pieces together.

The NGO Coordination Committee in Iraq is a network of about 80 International NGOs and 200 Iraqi NGOs. Its website carries weekly updates and some reports.
