A/HRC/36/63 B. Continued detention of a UNAMID staff member 26. The Independent Expert was informed about the case of Adam Abdulbari, a language assistant at UNAMID, who was arrested in Darfur by the national security officers on 23 November 2016 and transferred immediately to the National Security Service headquarters in Khartoum, where he was held in custody. In March 2017, Mr. Abdulbari was transferred to the Alnuza police station, where he remains detained under the supervision of the Attorney General for Crimes against the State. The UNAMID staff member is accused of undermining the constitutional system, waging war against the State, espionage against the country and terrorism. 27. The Independent Expert is concerned by the non-compliance by the Government of the Sudan with the provisions of the status-of-forces agreement between the United Nations and host countries. He calls on the Sudanese authorities to release Mr. Abdulbari as it appears that he is being detained for his work with UNAMID. C. Excessive use of force against Darfuri students in Khartoum and El Gezira States 28. The Independent Expert was made aware of incidents of attacks and arrests targeting Darfuri students in Khartoum and El Gezira States. According to information received, on 27 January 2017, officers of the National Security Service raided a student dormitory in Um Badda district in Omdurman housing mainly Darfuri students. Five of them were reportedly arrested for unknown reasons. On 21 March 2017, officers arrested 13 Darfuri students from the University of Holy Qur’an and Islamic Sciences in El Gezira State and used tear gas and batons to disperse a peaceful demonstration organized by them to protest against the university administration’s refusal to honour an agreement exempting the Darfuri students from paying tuition fees. The following day, officers raided the Darfuri students’ residence and arrested six of them. On 15 May 2017, officers and pro-government students attacked an assembly organized by the Darfuri student union alliance at Al-Azahri University, preventing the delivery of a speech calling for the full implementation of a feeexemption policy for Darfuri students agreed to by the Government of the Sudan during the peace talks in 2006 and 2011. Twenty students were arrested and taken to the central police station in Khartoum Bahri, where a case was filed against them for breach of public peace and public. The case was referred to the Central Bahri Public Order Court on 16 May and dismissed owing to lack of evidence. 29. The independent Expert expresses concern about the excessive use of force by the Sudanese authorities as a means to restrict the rights to freedom of expression, association and assembly, which are guaranteed by the Constitution of the Sudan and international human rights treaties to which the Sudan is a party. D. Restrictions on freedom of religion 30. Another area of concern that the Independent Expert discussed with the relevant stakeholders includes the need to ensure the protection of the freedom of religion, with particular reference to the demolition of churches and places of worship by the national security forces. On 7 May 2017, the Sudanese authorities destroyed the Sudanese Church of Christ building in the Soba al-Aradi area of Khartoum. On 17 May 2017, the Sudanese Church of Christ building in Agadisia in Khartoum was also demolished. While the Government alleged that the demolition fell under the authority of planning authorities and also included also mosques, schools and homes that had been randomly and disorderly constructed, the Independent Expert has yet to receive a list of mosques, homes and schools that were demolished in those areas. 31. The National Security Service has also been used to intimidate and arrest or detain Christian religious leaders. The Independent Expert had raised the issue in his discussions with government officials as a legitimate concern, which the Government of the Sudan needs to pay attention to, in view of the importance of the freedom of religion in a 6
