UN warns South Sudanese to flee deadly ethnic vendetta

The United Nations in South Sudan has warned villagers to flee from advancing fighters from a rival ethnic group.

Fighters from the Lou Nuer group are pursuing members of the Murle community as a deadly vendetta over cattle raiding continues.

The UN's deputy humanitarian co-ordinator in South Sudan, Lise Grande, told the BBC World Service that "several flanks of the attackers have moved in a south-easterly direction [from Pibor], almost certainly looking for cattle".

She added: "We are alerting civilian populations that the column is advancing so that they can take steps and flee for their lives so that they are not in harm's way".
