A/HRC/42/CRP.1 arms.326 They were interrogated and accused of affiliation with AQAP, but often torture was not accompanied by any such interrogation.327 243. At al-Tin there is no regular visitation allowed, and detainees have remained incommunicado or disappeared for up to two years. In exceptional cases, sporadic visits have been negotiated with Saudi and Government of Yemen authorities. 328 In cases where detainees were transferred to the Military Prison, visits were allowed only when money was paid to the guards.329 In all cases known to the Group, detainees were held for long periods without formal charge or legal proceedings. In March 2019, 10 detainees who had been at al-Tin since 2015 and 2016 were charged by the Public Prosecutor and transferred to alMounawara Central Prison.330 Detainees and family members were told by other detainees, or by Saudi and Government of Yemen authorities, that detainees were held accused of ‘terrorism’. In some cases, detainees were accused of links to the Sons of Hadramaut, a group of local men and boys who briefly controlled al-Mukalla until 2016, and who aligned with AQAP.331 Others were detained as hostages or based on local grievances.332 (g) Assab detention facility, Eritrea 244. Assab Detention Facility is located 12 km North of Assab city 333, in Southern Danakalia District, Southern Red Sea Region, and Eritrea.334 The facility is controlled by the United Arab Emirates and is adjacent to their Naval Base. It is located 2.5 km east of the United Arab Emirates Airbase in Assab.335 At the outset of the coalition intervention in the war in May 2015, the United Arab Emirates publically established these bases in Assab as locations from which it would undertake its intervention in Yemen. Stated activities taking place at the base included training the Security Belt forces.336 245. Witnesses identified United Arab Emirates military personnel as the guards and interrogators at Assab. They were a mix of Emiratis and non-Arabs of unidentified nationality or ethnicity, who wore United Arab Emirates military uniforms.337 In particular cases anti-United Arab Emirates fighters or fighters who had refused to work for Security Belt were disappeared to Assab and then coerced by United Arab Emirates military personnel to work for them in conducting assassinations. They were then transferred back to Yemen via al-Bureiqa or Bir Ahmed I and II.338 In 2018, there were at least nine male detainees witnessed at Assab, consisting of former Resistance, Security Belt members, and Houthi fighters.339 Based on reliable witness evidence and analysis of satellite imagery, the facility appeared at the time the image was taken to have at least 70 separate cells in which prisoners were kept.340 246. The lack of transparency over this facility renders a very real risk of ill-treatment, torture and other human rights violations. The Group of Experts received credible reports of torture in this detention facility, for which its investigations had not been completed at the time of writing.341 326 Confidential Sources on File.
