President Kenyatta, who is the Igad Rapporteur, will be joined at the summit by Ethiopia’s Prime Minister and Igad Chairperson Hailemariam Desalegn, Uganda’s Yoweri Museveni and Sudan’s Omar al-Bashir.
Igad has been mediating talks to end the 20-month old civil war between the government of President Salva Kiir and a faction led by rebel leader Riek Machar.
Dr Machar signed the Igad-plus compromise peace agreement in Addis Ababa, Ethiopia, on Monday last week.
President Kiir, who requested for a 15-day window to iron out outstanding issues, is expected to append his signature on the peace pact during the Juba summit.
The plane carrying the President and his delegation departed Jomo Kenyatta International Airport shortly before 9am and was seen off by the Chief of Defence Forces, General Samson Mwathethe, and senior government officials.
