South Sudan’s President Salva Kiir and rebel leader, Riek Machar signed a peace agreement in the margins of a regional summit in Ethiopia.
South Sudan plunged into warfare two years after gaining independence from Sudan in 2011 when a political dispute between Kiir and Machar exploded into military confrontation.
A previous peace deal signed in 2015 fell apart a year later after clashes broke out between government forces and rebels, forcing Machar to leave Juba.
The new agreement, mediated by Sudan, reinstates Machar, a former vice-president, to his former post.
The United States, Britain and Norway, known as the Troika which oversees peace efforts, welcomed the signature of the deal by Kiir, Machar and other groups.
