South Sudan on brink of 'ethnic civil war', says UN
In tonight's edition: the UN warns that troops are urgently needed to avert a Rwanda-like genocide in South Sudan. Also, Nigeria is going through the biggest economic crisis in its history, this as President Buhari announces the 2017 budget. And communities in DR Congo's North Kivu continue to live in fear of attack from militia groups. Many happen on roads inside Virunga National Park, where military convoys patrol in the hope of combatting the threat - we go on patrol with one of them.
