Though Sudan has accepted the notion of a joint U.N.-African Union peacekeeping force in Darfur, the operation could still be derailed by a lack of funding and political will, African Union chairman Alpha Oumar Konare said Sunday, according to AP. «What is lacking today in the implementation of the process is financial resources to put peacekeeping troops on the ground,» said Konare, who spoke at the opening session of the summit of the 53-member African Union. Many AU member states have said they don't have enough funds to outfit their soldiers for peacekeeping operations. The three-day summit in Ghana's capital is being attended by more than 30 heads of state, including the presidents of Nigeria, South Africa and Zimbabwe. The official topic of debate is a long-discussed, but elusive idea for a pan-African government. But immediate crises, such as conflicts in Sudan, Somalia and Chad, along with political turmoil in Zimbabwe, are expected to be addressed in private.
