Regional governments and international groups are trying to prevent Sudan and South Sudan's recent border clashes from escalating into full-scale war.
However, powerful drivers may be pushing the two countries into a confrontation. Among those factors are disagreement over the division of natural resources, ethnic tensions, and a tradition of mistrust between the two. South Sudan broke off last year from Sudan, after decades of unrest and civil war.
So far, the conflict has been constrained to limited, but nevertheless deadly, small-scale military actions from both countries. Airstrikes by Sudan have hit various points in the South.
