The United Nations human rights chief Navi Pillay has said the bombing of territory in South Sudan despite a UN resolution demanding an end to hostilities is an outrage.

She also called for a human rights monitoring mechanism in the border regions.

Aid agencies have warned of a deteriorating situation along the border and an increase in the number of people fleeing the bombings.
