Sudan and South Sudan were set to resume security talks late on Sunday, Dec 16, with Khartoum demanding that its southern neighbor cut ties with rebels on its territory, Reuters reported.

The two nations signed agreements in September to secure their disputed border and resume oil exports from the south after clashes brought them close to full-scale war in April. It was the worst violence since the South seceded last year under a 2005 peace deal that ended decades of civil war.
