The recent conflict between Sudan and South Sudan has seen civilians in border areas subjected to brutal attacks by both sides. However, as I found while in South Sudan last week, the impact of this conflict goes far beyond the disputed areas of Heglig or Abyei, threatening many more lives.
Prior to the most recent round of fighting, millions of Sudanese on both sides of the border were already displaced and vulnerable - from the restive Sudanese states of Blue Nile and South Kordofan, to South Sudanese villages emptied by tribal conflicts.
