A/HRC/28/80 6. Violations in the context of the escalation of hostilities 64. In a case monitored by OHCHR, in August 2014, a 28-year-old man suspected of treason was arrested by the Internal Security Agency and held in an unknown detention facility in Gaza for approximately 10 days. He was reportedly subjected to beatings and solitary confinement, and was denied access to a lawyer and family visits. He was subsequently transferred to an Agency prison in Ansar. Reportedly, his sister was detained in another detention facility on suspicion of treason and brought to an Agency detention facility for interrogation on several occasions, where she was allegedly tortured. 65. A total of 21 alleged collaborators were reportedly summarily executed by Palestinian armed groups in August 2014. Some of them were allegedly tortured prior to execution (see also A/HRC/28/80/Add.1, paras. 73-74). IV. Accession of the State of Palestine to international human rights treaties 66. In April 2014, the State of Palestine deposited instruments of accession to 20 international treaties, including seven human rights treaties and the Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict, the Geneva Conventions of 12 August 1949, Additional Protocol I to the Geneva Conventions and the Convention respecting the Laws and Customs of War on Land. Each accession was effected without reservations, a notable decision in a region with a large number of reservations to human rights treaties. Accession by the State of Palestine to the core international human rights treaties represents a significant strengthening of the legal framework for the protection and promotion of human rights in Palestine. The challenge will be to put these legal commitments into effect in law and in practice. 67. Since 2011, OHCHR has been working with the Ministry of Justice and the Ministry of Planning and Administrative Development of the Palestinian Authority to develop a rights-based framework for the national development agenda. A broad-based collaborative process produced a comprehensive 160-page guidance document setting out concrete recommendations on how to incorporate human rights more effectively into development programming. The document was finalized by the Government of the State of Palestine in January 2014. 68. Most of the recommendations in the guidance document were integrated into the Palestinian National Development Plan for 2014–2016, which was finalized in February 2014, providing a strong human rights-based framework in the four sectors covered by the Plan: social development, economic development, infrastructure and governance. The document was framed to provide guidance for integrating human rights into the Plan as well as in future Palestinian development plans. The document has been available to those involved in the damage and needs assessment exercise being conducted by the Government of the State of Palestine for the long-term reconstruction of Gaza after the escalation of July and August 2014. 69. Accession to international human rights treaties has provided an opportunity for OHCHR to build on its work with the Palestinian authorities, as well as with the Palestine Independent Commission for Human Rights and civil society, to ensure that the political commitments contained in the Palestinian National Development Plan are implemented in accordance with the legal commitments contained in the treaties. The Government has adopted a coordinated approach to its treaty reporting, which aims to draw on the linkages between treaty provisions and the Plan. With this approach, it is hoped that the initial treaty reports will provide a comprehensive baseline assessment for implementation of human 16
