Sudan Declares Emergency
Sudan has declared a state of emergency along its border with South Sudan. The measure follows a month of border fighting with South Sudan. This move imposes a trade embargo on the South and suspends the constitution. An emergency has already been in effect for almost a decade in Darfur. A similar status took effect in Blue Nile state last September when an ethnic insurgency began. Trade across the border has unofficially been banned since South Sudan's independence but the emergency formalises that prohibition.
