President Salva Kiir has appointed former Undersecretary of the Ministry of Humanitarian Affairs and Disaster Management Peter Gatwech Kulang as head of the Relief and Rehabilitation Commission.

This was through a Republican Decree read on the state-run TV, SSBC Friday evening.

Gatwech has replaced Manasseh Lomole Waya who was relieved in a similar decree announced on the SSBC on Friday.

Gatwech made the comeback to the Ministry after his relief from the role of undersecretary two years ago.

In a separate decree, Kiir relieved, Athieb Okech Ajang Ukech, the Peace and Security Advisor in Upper Nile State Government who hails from the SPLM party, and replaced him with Joakino Fideli.
