The situation in Sudan is very volatile at the moment. The expected indictment by the International Criminal Court (ICC) against president Omar al-Bashir seems to be imminent. At the same time, the peace deal between the North and the South of the country seems to be breaking up.
It is not unlikely that Bashir will try to get the North in his pocket, thus avoiding any chance of being handed over to The Hague, by pointing to the 'enemies within'. A fullblow civil war may be in his advantage in this stage in order to ensure that he stays in place.
