Washington on Wednesday called on Sudan's military rulers to "desist from violence" and urged talks with protesters to resume, after doctors said 108 people had been killed in a crackdown.
"The United States condemns the recent attacks on protesters in Sudan," State Department spokeswoman Morgan Ortagus said in a statement.
It called on the ruling military council and Rapid Support Forces paramilitaries to desist from violence and "a civilian-led transition that leads to timely elections and free expression of the will of the Sudanese people," Ortagus said.
"Senior Department officials are engaging now with officials in the region and we welcome the recent statements from the AU, Egypt, and Saudi Arabia calling for restraint from violence and resumption of dialogue," she added.
Riyadh, a major backer of the military rulers, had earlier sought a resumption of "dialogue between the various parties of Sudan."
