Security Council, the government forces were supported by JEM fighters and the clashes resulted in further civilian displacement. Potential UNESCO World Heritage site On 3 October 2017, the government of South Sudan submitted the name of the historical site of the slave camp to the UNESCO World Heritage Centre to be included on its first ever Tentative List of potential World Heritage sites. The UNESCO report detailed the following:"Zubeir Rahma constructed a trench and a fortification where slaves were kept awaiting to be transported to various destinations along the Nile northwards. The trench was built underground almost four meters deep and three kilometres long; wood and mud were used in the construction. The trench contains rooms used as prisons to confine the slaves, and on its edge is a tree renowned as a hanging place for slaves who attempted to escape from their captors. [..] Today, the Deim Zubeir slave trench is located by the present day main road from Wau to Raja in Wau County. It is not well maintained and needs urgent safeguarding to preserve its importance as a cultural heritage site. The tree that was notorious as the site of slave hangings remains next to the trench." In its statement on authenticity and integrity, UNESCO added:"The chiefs of the community in the Payam are also involved in collecting information and data about the site, including how it was affiliated with the former inhabitants' lifestyles and cultures. However, additional support is needed from historians and anthropologists to look into the shape and content of the trench, which is currently underground and unexcavated."Historical items from Deim Zubeir are scattered across European museums. Artefacts taken as a trophy by Romolo Gessi were sold by his widow to the Museum of Ethnography and Prehistory in Rome. Parts of the collection were later transferred to other museums in Italy. In June 2019, UNESCO supported a field-mission to Deim Zubeir of South Sudanese expert Elfatih Atem, who is also director of a national non-governmental organisation, the Likikiri Collective, which has specialised in conducting oral history research. Atem worked "to collect material evidence, photos of the landscape and narratives of slave trade and legacy of slavery at the site as part of South Sudan's efforts to justify its potential criteria for World Heritage listing. During his consultations, he raised awareness of the World Heritage Convention as well as the responsibilities and opportunities linked with
