Ugandan special forces have been deployed to South Sudan's capital, the Ugandan army chief said Tuesday, after rising tensions that have threatened a fragile peace agreement.

Impoverished South Sudan has long been plagued by political instability and insecurity, but concerns have risen sharply in the past week after clashes between forces allied to the country's leaders in the northeast.
