As US weighs lifting Sudan sanctions, South Sudan a concern
None
As the United States considers lifting sanctions on Sudan, South Sudan's government accuses its neighbor of supplying weapons to rebels in its bloody civil war.
The Associated Press has spoken with rebel fighters who recently defected, and they describe how weapons flow across the border.
Arms experts have documented past support from Sudan to the rebels, but they say proving recent transfers is extremely difficult amid the chaos.
Sudan's government has denied arming the rebels. Human rights groups disagree and say Sudan's actions should weigh heavily against lifting sanctions.
The opposition rejects the claims that Sudan is supplying it with weapons.
