104 INTERNATIONAL LEGAL PROTECTION OF HUMAN RIGHTS IN ARMED CONFLICT urged “all parties to armed conflicts to comply with their obligations under international humanitarian law, in particular to ensure respect for and protection of the civilian population, and also urges all States to comply with their human rights obligations in this context”.155 This resolution may be seen as the cornerstone of the Human Rights Council’s work on the protection of human rights in conflict situations. The Human Rights Council has followed the same approach. It also reiterated “that effective measures to guarantee and monitor the implementation of human rights should be taken in respect of civilian populations in situations of armed conflict, including people under foreign occupation and that effective protection against violations of their human rights should be provided, in accordance with international human rights law and applicable international humanitarian law”.156 Finally, since 1989 the Sub-Commission on Prevention of Discrimination and Protection of Minorities, as it was then known, has also insisted on the need to respect obligations of both international human rights law and international humanitarian law in armed conflict. In its resolution 1989/24, it deplored the frequent lack of respect during armed conflicts of relevant provisions in international humanitarian law and the law of human rights. Furthermore, in 2005 it issued a working paper on the relationship between human rights law and international humanitarian law, particularly from the perspective of their dual or simultaneous application in the light of the case law of human rights treaty bodies and special procedures.157 E. THE OFFICE OF THE UNITED NATIONS HIGH COMMISSIONER FOR HUMAN RIGHTS The field-based activities of OHCHR illustrate how it addresses obligations of both international human rights law and international humanitarian law   Resolution 2005/63.   Resolution 9/9. 157   E/CN.4/Sub.2/2005/14. 155 156
