A/HRC/42/CRP.1 642. Considering the evidence obtained, and the marginalized status of these survivors in Yemen, in a context of already widespread impunity, the Group has reasonable grounds to believe that the Security Belt forces and members of the 35 th Armoured Brigade are targeting victims on the basis of their caste, class or other marginalized status. Furthermore, in 2019 an increasing proportion of women and children are vulnerable and at risk of gender-based violence. Security Belt forces have conducted large-scale detention of migrants including women and children, and the Group of Experts has received reports of sexual violence by linked armed groups in neighbouring areas and against displaced persons. The parties also continue to proliferate similar armed groups in southern and western Yemen.999 643. Further investigation is required as to the scale and organized nature of such targeted sexual violence, perpetrated by these and other armed groups in marginalized communities, including displaced persons, under Government, United Arab Emirates, and de facto authority control. (c) Sexual Violence in detention “Every time I didn’t confess or didn’t say something in the exact way they wanted he inserted his penis in my mouth. I have had no psychological support or seen a doctor. I am still so damaged.” Former al-Bureiqa coalition base detainee1000 644. During 2016-2019 the parties have used sexual violence in detention to torture, physically harm, traumatise, humiliate, and subjugate detainees. The Group has verified 24 cases of sexual violence in detention by several parties. 645. This includes 12 cases of sexual violence in the de facto authority detention facilities, consisting of sexual violence against five women, six men, and one boy. In the cases related to men and boys, their testicles were beaten, tied, or had heavy objects hung from them, and forced nudity was used. There were also threats of rape against detainees and their wives, and unverified reports of rapes of boys.1001 646. This also includes at least 12 cases of rape of six men and one boy in United Arab Emirates detention facilities, as well as other sexual assaults, and forced nudity. Detainees were raped anally and orally, including penile rape, rape with objects, and gang rape. Sexual assaults included the beating of detainees’ testicles.1002 In addition in 2018, the Group verified that in March 2018, nearly 200 detainees were stripped naked in a group while personnel of the United Arab Emirates forcibly examined their anuses. During this search, multiple detainees were raped digitally and with tools and sticks. 647. Detainees reported that the violence and threats used would escalate, and the ultimate threat was of rape. When the de facto authority or Emirati interrogators did not succeed with other means, they would sexually abuse detainees with escalating severity. In all cases described above sexual violence was used to humiliate detainees, and coerce them to make confessions or to comply with demands. Rape and other forms of sexual violence for perpetrators are primarily a means of gaining power and control. Interrogators and guards used these methods against women, men and boys to dehumanise and ‘dishonour’ them, and in the cases of men and boys ‘emasculate’ them, in order to achieve their aims.
