S. Sudan rebel leader Riek Machar arrives in Juba, first time since 2016
Machar, the former vice president, fled to the neighbouring Democratic Republic of Congo in 2016 after fierce fighting broke out in Juba, killing hundreds of people. He later travelled to South Africa, where he was held under house arrest until earlier this year. Last month he and President Salva Kiir signed a new peace deal in the latest attempt to end the five-year war.
