President William Ruto has appointed former Prime Minister Raila Odinga as Kenya's special envoy to South Sudan following the arrest of the country's first Vice President, Riek Machar.

Odinga is set to depart the country for South Sudan on Friday, 28 March, for peace talks aimed at preventing further escalation of conflict in the war-torn country.

The development followed moments after the Head of State spoke with South Sudan President Salva Kiir, his Ugandan Counterpart Yoweri Museveni and Ethiopian Prime Minister Abiy Ahmed.

During the phone call, President Ruto noted that he would be sending a special envoy to South Sudan to engage, attempt to de-escalate the conflict, and provide feedback.
