United Nations Secretary-General Ban-Ki-moon has said, there is a real risk of mass atrocities being committed in South Sudan, following a sharp rise in hate speech and ethnic incitement. <br/><br/>In a report to the Security Council released yesterday, Mr Ban said, UN peacekeepers in South Sudan lack the manpower and capability to stop mass atrocities should they occur. In the report, Ban repeated earlier calls on the Security Council to impose an arms embargo on the country which he said is inundated with weaponry.<br/><br/> He also said, government restrictions on the peacekeepers movements have led to mission paralysis and are undermining humanitarian operations in the world's youngest nation.<br/><br/>South Sudan has been riven by ethnic violence since shortly after gaining independence from Sudan in 2011. Tens of thousands have been killed and over 2 million displaced.
