i found that Sudan map is not updated , (WEST Kordofan State) is not included in the map of the states of the Sudan;
which is published in the following link to be used as source map for web based data visualization projects

We will be very thankful if the Sudan map is updated. The up to date map is attached in geojson format. and also the map image included in the link of the official UN website https://www.unocha.org/sudan.
