Rebels say there is no going back.
March first is the deadline for relief groups to sign the new agreement. Those who have not will not be allowed to operate in rebel-held areas. Those who have not signed include some of the biggest names in the aid business - Medecins sans Frontier, Save the Children, CARE, and Oxfam. Those groups also object to provisions allowing rebels to decide what kinds of programs go where. Millions of people in the south depend on food aid.
