"The belligerents, who have demonstrated they are not fit to govern, must end the conflict and transfer power to a civilian transitional government," Godfrey said in a statement.
"The comments reflect the US ambassador's lack of respect for the Sudanese people and their independence," the ministry said, adding: "The comments ignored the fact that the armed forces, the National Army of Sudan, are defending the country and its people against a terrorist and criminal militia."
"We expect the US ambassador and his country's government to correct this unbalanced and defective position, and for the envoy to distance himself from comments that contradict diplomatic norms and rules and do not help to end the crisis in our country," read the statement.
