A/HRC/RES/39/15 5. Strongly condemns all violations and abuses of international human rights law and all violations of international humanitarian law committed by all parties to the conflict, including the continued systematic, widespread and gross violations and abuses of human rights and all violations of international humanitarian law by the Syrian authorities and affiliated militias, including foreign terrorist fighters and those foreign organizations fighting on behalf of the Syrian authorities, and expresses deep concern that their involvement further exacerbates the deteriorating situation in the Syrian Arab Republic, including the human rights and humanitarian situation, which has a serious negative impact on the region; 6. Also strongly condemns the continued use by the Syrian authorities of banned munitions, the indiscriminate use of heavy weapons in populated areas, barrel bombs, aerial bombardment, incendiary weapons, ballistic missiles and cluster bombs, and the use of starvation and siege directed against civilian populations as a method of warfare, and stresses the particular situation of concern in Idlib, where increasing violence and airstrikes continue to cause death and injury among civilians; 7. Urges an immediate end to the violence in Idlib, and respect of the deescalation area, in order to prevent further death and injury among civilians and damage to civilian objects, as well as to avoid a potential humanitarian catastrophe; 8. Strongly condemns all attacks on medical and health personnel, first responders, their means of transport and equipment, and hospitals and other medical facilities, and deplores the long-term consequences of such attacks for the population and health-care systems of the Syrian Arab Republic; 9. Also strongly condemns the attacks against civilian objects, such as schools, as reported by the Commission of Inquiry, and the negative effects of the ongoing conflict on the rights and welfare of children, including their access to schools, medical care, education and humanitarian assistance, decries the violations and abuses of international human rights law and violations of international humanitarian law, as applicable, and deplores, in particular, the impact of the denial of humanitarian access on their lives and well-being; 10. Urges all parties to the conflict to comply with their respective obligations under international human rights law and international humanitarian law, and demands that all parties, particularly the Syrian authorities and their State and non-State allies, refrain from carrying out attacks against the civilian population and civilian objects, such as schools, as well as on medical units, personnel, patients and transport and personnel involved in humanitarian assistance; 11. Expresses deep concern at the finding of the Commission of Inquiry that tactics used in the recapturing of the besieged area of eastern Ghutah amounted to war crimes and crimes against humanity; 12. Also expresses deep concern about the human rights situation and humanitarian access in areas that have recently come under the control of the Syrian authorities, and urges them and their allies to ensure humanitarian access and respect for international human rights law and international humanitarian law; 13. Expresses its profound concern at the findings of the Commission of Inquiry that sexual and gender-based violence against women, girls, men and boys has been a persistent issue in the Syrian Arab Republic since the uprising in 2011, and that women and girls have been disproportionately affected and victimized on multiple grounds; 14. Notes the findings of the Commission of Inquiry that such acts of sexual and gender-based violence were committed most commonly by Syrian authorities and associated militia, as well as by the so-called Islamic State in Iraq and the Levant (Daesh), that they form part of a widespread and systematic attack directed against a civilian population, amounting to crimes against humanity, and that, after February 2012, these acts constitute the war crimes of rape and other forms of sexual violence, including torture and outrages upon personal dignity; 3
