The East African regional bloc Igad has called for the South Sudanese rebel leader Riek Machar to be released from house arrest as soon as possible.
Mr Machar has been in the South African capital Pretoria for more than a year. Igad said he should be freed only if he renounced violence and did not obstruct the peace process.
It said he should be allowed to relocate to any country that did not border South Sudan.
The country has been in conflict for more than four years, with tens of thousands killed and millions displaced.
