Since the 30th session of the UN Human Rights Council, Amnesty International has conducted further research on violations in the context of the conflict in Yemen, including a field mission in November 2015. Amnesty International has gathered evidence, over the course of four field missions to Yemen since May 2015, that all parties to the conflict have committed violations of international human rights law and international humanitarian law. Since the beginning of the conflict in March 2015, Amnesty International has investigated over 30 air strikes in Sana’a, Hodeidah, Hajjah and Sa’da, their circumstances and impact. Amnesty International found that the Saudi Arabia-led coalition continued to commit violations of international humanitarian law, including by the apparently deliberate targeting of civilian objects such as hospitals, schools and factories. Meanwhile, since November 2015 the Huthi armed group and its allies have imposed restrictions on medical aid and goods essential for the survival of civilians in Ta’iz and shelled civilian areas. They have also carried out arbitrary arrests, detentions and abductions of government supporters, journalists and human rights defenders, and curtailed freedom of association by closing down NGOs.
