At least 15 people including senior officials have been killed in an ambush in South Sudan.

Officials say the commissioner of Boma county in Pibor was returning from a visit to a village on Tuesday, when youths from a rival community attacked .

He was killed along with his bodyguards and Boma’s deputy army commander.

A 2018 peace deal ended a five year civil war in South Sudan.

But several areas including Boma county have experienced outbreaks of ethnic violence.

These have often been revenge attacks for cattle raids, involving the Murle, Anyuak, Nuer and Dinkas ethnic groups.
