The South Sudanese army has announced it will investigate allegations of rape of women and girls from the Nuer ethnic group by government troops. Earlier in July, witnesses and civilian leaders warned soldiers allegedly raped "dozens of ethnic Nuer women and girls" who had sought shelter at a UN base after being displaced by recent violence in the capital Juba.
Military spokesman Lul Ruai Koang said the army was taking "the whole accusation very seriously."
Witnesses told AP news agency that at least one incident occurred as Nepalese and Chinese peacekeepers were looking.
"They were seeing it. Everyone was seeing it," the witness, who spoke on conditions of anonymity, said. "The woman was seriously screaming, quarrelling and crying also, but there was no help. She was crying for help."
The UN confirmed at least 120 cases of sexual violence have occurred in Juba since civilians fled their homes following fighting which led to at least 300 deaths at the beginning of July.
UN spokesperson Farhan Haq said the UN peacekeeping mission in South Sudan (Unmiss) received "deeply disturbing reports of sexual violence, including rape and gang rape, by soldiers in uniform and men in plain clothes against civilians, including minors, around UN House and in other areas of Juba."
The reports came as rebel leader and former vice-president Riek Machar was dismissed after he fled Juba. A section of the Sudan People's Liberation Movement-in-Opposition (SPLM-IO) appointed Taban Deng Gai, minister of mining and SPLM-IO former chief negotiator as the acting vice president. However, Machar deemed the new appointment as illegal.
Machar had fled South Sudan in 2013, when the country descended into civil war. His return earlier this year and his reinstatement as vice-president had restored hopes for the implementation of a peace process signed in August 2015. However, tensions have been running high since Machar's return.
Some analysts have pointed out the replacement could create fractures within the opposition with a group supporting Machar and the other supporting Gai. This, coupled with the recent resurgence of violence, is sparking fears that South Sudan could be plunged back into civil war.
