South Sudan's President Salva Kiir and rebel leader Riek Machar have agreed a peace deal after a five-month conflict.

The deal calls for an immediate truce and the formation of a transitional government ahead of the drafting of a new constitution and new elections.

The conflict in the world's newest state has left thousands dead and more than one million homeless.

US Secretary of State John Kerry said the deal "could mark a breakthrough for the future of South Sudan".
