Birmingham University lecturer of International Development says the world is losing patience with South Sudan as refugee crisis deepens.
Jonathan Fisher laments that the humanitarian situation on the ground is deteriorating as the two sides are focusing on defeating each other.
He expresses grief that the heavy fighting in Unity State forced all UN agencies and NGOs to evacuate their staff from parts of the region.
Mr Fisher says the fighting would apparently leave around 300 thousand people in desperate need of emergency relief without any access to food and medical services.
