The Special Representative of the UN Secretary-General warned all South Sudanese and parties against any community motivated violence.
In a statement issued on Tuesday, Hilde F Johnson warned that the current violence should not assume ethnic dimensions.
She called on national, community leaders and all political factions to refrain from any action that fuels ethnic tensions and exacerbates violence.
The Special Representative urged all citizens and leaders to guard against any provocative actions or violence against particular community.
She appealed to all parties to seek a peaceful resolution to the current crisis.
Ms Johnson said it was more important for the government to have discipline, command and control in the security forces.
