| Sudan's government refused to sign a security deal with rebels on Friday designed to end violence in the western Darfur region, saying the document drafted by African Union mediators was too one sided. But the mediators said the talks in Nigeria's capital Abuja were set to resume at 1400 GMT and that they hoped for agreement by the weekend. Rebels said they were willing to sign the plan. The slow-moving talks on ending the Darfur conflict, which the United Nations says has triggered the world's worst humanitarian crisis, have been plagued by accusations of ceasefire violations between the two sides. A revolt began in the arid Darfur region in February 2003 after years of low-level fighting between mainly African farmers and Arab nomads over scarce resources. |
