Sudanese authorities have declared an overnight curfew in two towns in southeastern Blue Nile state, close to the border with Ethiopia, after several days of tribal clashes that they said had left 31 people dead and 39 injured.
Clashes spread in several towns from Wednesday after the killing of a farmer, before security forces made arrests and brought the situation under control, a statement from Blue Nile state's regional government said.
The statement said 16 shops had been destroyed and a night curfew was declared in the towns of Damazin and Roseires.
