Challenges remain for Bashir after Sudan unrest

Sudan says it has freed female prisoners detained after two weeks of fuel protests in September. At least 50 people were killed in what became the worst unrest of President Omar al-Bashir's 24 years in power. Peace has not returned, but challenges to the president remain - not least within his own party. Al Jazeera's Hodan Abdel Hamid reports from Khartoum.
