In South Sudan, Vote to Secede Looms
As Sudan gears up for Sunday's national elections, another landmark vote is on the horizon -- a referendum in January that will determine whether the south splits from the north.
Like the elections, the referendum is a key requirement of the 2005 Comprehensive Peace Agreement, intended to give southerners a chance to decide if they will remain in a unity government with the north, or become an independent country.
But several major related issues are still up in the air, including where the north-south border actually is.
