The world’s attention was rightly seized by the terrible conflict in Sudan’s western region of Darfur, in which hundreds of thousands of civilian lives were lost. It is often forgotten, however, that the tragedy of Darfur came after Sudan’s north-south conflict, Africa’s longest running civil war, in which more than 2m people were killed. On Friday it is five years since the historic Comprehensive Peace Agreement was signed between north and south Sudan, yet there is a real threat of all-out war returning to Sudan and still no permanent resolution to the Darfur conflict.
