We, the undersigned nongovernmental organizations, urge you to support the creation of an independent international investigation into violations and abuses of international human rights law and international humanitarian law in Yemen since the start of the current conflict. This is a call that has been made since 2015 by national, regional, and international civil society organizations, the United Nations High Commissioner for Human Rights, and the Security Council Panel of Experts on Yemen. The number of abuses, and the need for credible international investigations, has only increased since 2015.
