South Sudan's Riek Machar is a veteran rebel who has survived years of bush warfare, assassination attempts and exile and now faces charges of treason and crimes against humanity.

Until this month, Machar was South Sudan's first vice-president under a fragile power-sharing agreement designed to stop the country slipping back into civil war.
