KHARTOUM (AFP) - A South Sudan rebel group led by renegade general Peter Gadet has agreed to an unconditional ceasefire and is committed to talks on merging its troops with the army, its spokesman said on Wednesday. "We are declaring a ceasefire and we are also accepting the amnesty offered by the president as the basis of talks with the government of S Sudan," Bol Gatkouth told AFP, speaking on behalf of militia group. "The decision came after pressure from our international friends, and the call of the S Sudanese people that the govt is serious about reconciliation," he said.
