N'DJAMENA, April 25 (Reuters) - Chad's ruling military council has rejected an offer from northern rebels for a ceasefire and talks, calling them "outlaws" who needed to be tracked down and arrested for their role in the battlefield death of President Idriss Deby.
The rebels, known as the Front for Change and Concord in Chad (FACT), said on Sunday that they were ready to discuss a political settlement, two weeks after they poured over the border on election day demanding an end to Deby's 30-year rule.
