The African Union said at a meeting in Addis Ababa, Ethiopia last week that it would send a group of monitors to Sudan's western Darfur region, where severe conflict has resulted in the outpouring of some 110,000 refugees into Chad and the displacement of hundreds of thousands. The military observers, from Ghana, Senegal, Namibia and Nigeria, will be there to see that a 45-day cease-fire is carried out among militia groups, government soldiers and rebel fighters, so that aid workers can more easily assist the suffering.
