Fears grow of return to civil war in South Sudan after vice-president’s detention

Placing of Riek Machar under house arrest comes after period of rising tensions and armed clashes

South Sudan's first vice-president and main opposition leader, Riek Machar, has been placed under house arrest, prompting a warning from the UN that the country is at risk of relapsing into widespread conflict.

Machar's party said the arrest has effectively collapsed the peace deal that ended the 2013-2018 civil war.
