Following the death of late Chadian President Idriss Deby, Chad has imposed curfew and shuts its borders.
The announcement came a day after provisional election results projected late president Idris Debby would win a sixth term in office.
Déby was one of Africa’s longest-serving leaders after becoming president of Chad through charter 1991.
Deby’s son, Mahamat Idriss Déby Itno is expected to lead the council but “free and democratic” elections will be held once the transition period is over, the army said on Tuesday.
