The trial of former South Sudan Vice President Riek Machar began on Monday in the capital, Juba. Machar, alongside the coaccused, was presented in a cage inside the courtroom. This was the first time Machar appeared in public since he was placed under house arrest in March. Both Machar and President Salva Kiir are not on good terms. Kiir hails from the Dinka, the largest ethnic group, while Machar hails from the Nuer, the second largest.
