Sudan: Darfur force could fail if problems not settled-UN

A planned U.N.-African Union peace force for Darfur could fail unless disputes with Sudan over its make-up are resolved and key specialized units found, the top U.N. peacekeeping official has said. The 26,000-member force aims to bring security to the western Sudanese region after 4-1/2 years of conflict between government forces, allied militias and rebels. Even before its full deployment, it is meant to take over from an overwhelmed AU force of 7,000 at the end of this year.
