Disputes - international:
the north-south civil war has drawn Sudan's neighbors into the
fighting, sheltering refugees, and infiltration by rebel groups -
Kenya and Uganda have acted as mediators; Sudan accuses Eritrea of
supporting Sudanese rebel groups; efforts to demarcate the porous
boundary with Ethiopia have been delayed by fighting in Sudan;
Kenya's administrative boundary still extends into the Sudan,
creating the "Ilemi triangle"; Egypt and Sudan retain claims to
administer the triangular areas that extend north and south of the
1899 Treaty boundary along the 22nd Parallel, but have withdrawn
their military presence; Egypt is economically developing the
"Hala'ib triangle"
