One woman was killed and three other civilians were wounded on Monday in rebel shelling around the state capital of war-torn South Kordofan state, Sudan's army said.

"This morning a group from SPLM-North tried to get inside Kadugli town and they shelled an area six kilometres (four miles) east of Kadugli. As a result of this a woman was killed and three citizens injured," Sawarmi Khaled Saad, the Sudanese army spokesman, told AFP.
