FASHER, Sudan, Aug 6, SPA-- Senegalese President Abdoulaye Wade on Sunday appealed to rebels in Sudan's violence-torn Darfur region to join a peace accord to stop the conflict from spreading wider in central Africa, Reuters reported. In a visit to Darfur's main town, Wade directed his appeal to the two Darfur rebel groups that have not signed an African Union-backed May peace deal for the turbulent western region. Wade, who is visiting Sudan and Chad to defuse tensions between the two feuding neighbours, has invited their presidents to peace talks in Dakar on Wednesday. He extended this invitation to the Darfur rebels still holding out. "I ask these other factions to come and meet me in Dakar so that together they can join the accords. In that way, we can all work for peace in Darfur," he told reporters.
