One policeman and three protesters were killed in Sudan Khartoum and many other demonstrators were wounded, state TV said.
The Transitional Military Council (TMC), which took over after the army overthrew President Omar al-Bashir in April blamed the violence on saboteurs who demonstrated discontent with the transition deal.
After the incidents Sudan’s ruling military council warned that it would not allow “chaos”. Four people were killed in violence that broke out over an agreement on a political transition reached by the generals and protest groups.
