Pope Francis flew out of Democratic Republic of Congo on Friday, heading for neighbouring South Sudan, where he will remain until Sunday.
The Archbishop of Canterbury, Justin Welby, and the Church of Scotland Moderator, Iain Greenshields, will be with him during the South Sudan leg of his journey, an unprecedented joint "pilgrimage of peace" by the three Christian leaders.
