He also calls on the warring parties to end hostilities and implement the Peace Agreement they signed in August 2015.
He adds that the national dialogue declared by President Salva Kiir last year should be inclusive for all communities in the country to participate to end the current crisis.
The government will investigate the killing of the aid workers, says Martin Elia, Lomurö Minister of Cabinet Affairs.
The United Nations on Sunday said six aid workers were ambushed and killed over the weekend on Juba-Pibor road.
