At least 19 people were killed in a flare-up of fighting between nomadic herders and sedentary farmers in south Chad last week, authorities said.
Deadly inter-communal conflicts are relatively frequent in Chad, mainly between herders and local farmers who accuse them of grazing animals on their farmland.
Chad, a regional power and ally of the West against Islamist militants in West Africa, has been in turmoil since ex-president Idriss Deby was killed on the frontline against rebels in the north last year.
