How many people have been estimated to be dead in the conflict?

United Nations Secretary General Ban Ki-moon says stopping the killing and finding a political solution in the Darfur region of Sudan remain his highest priorities. After increasing international pressure, the Sudanese government last month agreed to allow a combined 20,000-strong peacekeeping force, made up of the U.N. and the African Union, into Darfur. Mr. Ban said that was progress. It is estimated that some 200,000 people have died in Darfur’s ethnic and political conflict since 2003. Mr. Blair has been named the representative of the Middle East Quartet, which is made up of the United States, the European Union, the U.N. and Russia.
