“South Sudan is on the brink of a return to full-scale civil war - and this civil war could be on a much larger scale than we’ve seen in the past.”

What’s going on in South Sudan? This week alarm bells have been ringing after leading allies of the Vice President, Riek Machar, were arrested – and Machar’s own home in Juba was surrounded temporarily by troops.

It follows clashes between a militia called the ‘White Army’ which fought alongside Machar during the civil war, with government troops in Upper Nile state, close to the Ethiopian border.

The relationship between Machar and President Salva Kiir has always been fractious and in 2013 a bloody civil war broke out after their political differences spiralled. 400,000 people were killed and 2 and a half million were displaced.

So is the peace deal which ended that war in 2018 now under threat?
