At least 100 people have been killed in a two-day crackdown on Sudanese protesters carried out by soldiers and paramilitaries, a doctors' committee close to the demonstrators said on Wednesday.
It said at least 326 people were injured and that most required urgent surgical intervention and intensive care.
Forty bodies were pulled out of the Nile River near the capital Khartoum, the doctors' committee said on Wednesday.
Sudan's main opposition group has called for an international inquiry into the killing of the protesters.
Sudanese Professionals' Association (SPA) spokesperson Amjad Farid said it rejected a plan to set up a governmental investigative committee, as announced by Lieutenant General Abdel Fattah al-Burhan, the head of the Transitional Military Council.
Violence in the country began Monday when soldiers fired at demonstrators with the command of the Sudan Transitional Military Council.
The military council has ruled the country since the ousting of President Omar al-Bashir on 11 April, following months of protests against his three-decade authoritarian rule.
