South Kordofan Gov. Ahmed Haroun said six women were killed in an attack by a rebel Sudanese movement on Kadugli, the independent Sudan Tribune reports.
The report identified a state radio station, police headquarters and the offices for UNICEF as targets of the attack.
A military spokesman said rebel forces infiltrated security blockades, adding the assault was likely a response to Sudanese targeting of militants in the area. The United Nations described the attack as "indiscriminate."
The attacks came as regional leaders met in the state to discuss efforts to resolve issues left over from a peace deal reached in 2005.
South Sudan became an independent country as part of the peace deal. Ethnic fighting, disputes over oil revenue and unsettled border issues have threatened the fragile peace, however.
