South Sudan fails to withdraw troops from Sudan border

JUBA (Reuters) - South Sudan is not withdrawing troops from the border with Sudan to set up a buffer zone as it pledged it was last month, South Sudan's army said on Monday, in a setback to efforts to resume the oil exports vital to both economies.

The two countries came close to war last April in the worst border clashes since South Sudan seceded in 2011 under a peace deal that ended one of Africa's longest civil wars.
