Senegal's President Abdoulaye Wade says the leaders of Chad and Sudan will sign peace accords next week at a summit in Dakar.
Mr. Wade told reporters in Paris Friday that Chadian President Idriss Deby and Sudanese President Omar al-Bashir will agree to stop supporting rebel groups on each other's territory.
He said the signing will take place March 12, before the start of a summit of Muslim leaders.
Chad has accused Sudan of backing the rebels who attacked Chad's capital N'Djamena last month. Chadian President Deby said earlier Friday that the fighting sparked by that attack killed 700 people.
Sudan, for its part, accuses Chad of aiding rebels in Sudan's war-torn Darfur region.
Mr. Deby and Mr. Bashir signed a peace agreement at the urging of Libya in 2006 but the agreement quickly broke down.
