A/HRC/28/80 2. Wide-scale arrest campaigns against social activists and Fatah members and supporters 52. Many Fatah members and supporters across the Gaza Strip were reportedly summoned or arrested by the Internal Security Agency and questioned about Fatah’s plans to mark the anniversary of the death of Yasser Arafat on 11 November 2013. 53. Alleged members of Salafist groups were also subjected to arbitrary arrest and detention by the Internal Security Agency. From 4 to 6 March 2014, the Agency arrested without warrant two people suspected of organizing an attack targeting a church in the south of Gaza. One of them was accused of being affiliated with the Islamic State group. 54. OHCHR also documented several cases related to the arrest, reportedly without a warrant, of persons suspected of treason. The absence of a legal warrant is one illustration of a wider pattern of abuse by the Internal Security Agency and of violations of the rights of persons deprived of their liberty. 3. Torture, ill-treatment and violations of due process 55. Many detainees held in detention by the Internal Security Agency were allegedly subjected to torture and ill-treatment upon arrest and during interrogation. Torture methods included beating with sticks, sensory deprivation (blindfolding), shabeh, solitary confinement and intimidation. Gazan security agencies appeared to use harsher interrogation techniques with detainees suspected of treason. 56. In a case monitored by OHCHR, in February 2014, a 27-year-old man accused of treason was arrested by the Internal Security Agency. He was detained and transferred to the civilian prison in Al-Katiba, west of Gaza city, where he was held for another six days. He claimed that, during interrogations, he was beaten with a rubber stick and forced into shabeh. He was reportedly detained in solitary confinement with the aim of obtaining information on his alleged collaboration with Israel. Following his transfer back to the Agency detention facility, he was held again in solitary confinement. He was allegedly denied access to a lawyer and family visits. 57. In a similar case, in March 2014, a 38-year-old man suspected of treason was arrested by the Internal Security Agency. He was reportedly held in solitary confinement and threatened with hanging. Although he was permitted to see the prosecutor, who extended his detention for 15 days, he was denied the right to contact his wife and a lawyer. Moreover, he was reportedly denied access to medical treatment while suffering from a serious liver illness. 58. Alleged members of the Tamarod movement (see A/HRC/25/40, para. 65) arrested in November 2013 were also allegedly subjected to beatings on the hands and feet with a stick, punching, shackling for extensive time periods and shabeh. A 16-year-old youth suspected of being affiliated with Tamarod was arrested by the investigation police and was held in detention for two days before being released. He was allegedly subjected to beatings on the soles of the feet, shabeh and sleep deprivation. The victim reported to OHCHR that nine other people were in detention on the same charges during his detention. He had been detained on previous occasions for similar accusations. Some Fatah members also alleged that they had been subjected to ill-treatment during detention. In March 2014, a 21-year-old Fatah member was held in detention for several hours by the investigation police owing to his participation in a demonstration supporting the Israeli-Palestinian peace process. He was reportedly held in solitary confinement and slapped in the face numerous times, forced to stand on a wet and dirty floor, and verbally abused. He was subsequently released with no charges. 14
