With Sudan’s army suspending participation in the Jeddah ceasefire talks, Mr Elbadawi is very concerned about his motherland that was once touted as a beacon of hope in the region.

The former World Bank economist argues that once peace is restored, then the pursuit of justice should quickly follow.

"It is important to investigate the reason why this conflict started to begin with. There are people spoiling for a conflict and there should be sanctions on this group," he added.
