I am deeply alarmed by the ongoing fighting in Juba between soldiers of the Sudan People's Liberation Army (SPLA) and the SPLA in Opposition. This outbreak of hostilities in the capital, on the eve of the country's fifth anniversary of independence, is yet another illustration of the parties’ lack of serious commitment to the peace process and represents a new betrayal of the people of South Sudan, who have suffered from unfathomable atrocities since December 2013.
