(Beirut, September 25, 2018) – The Houthi armed group in Yemen has frequently taken hostages and committed other serious abuses against people in their custody, Human Rights Watch said today. Houthi officials should stop taking hostages, free everyone arbitrarily detained, end torture and enforced disappearances, and punish those responsible for abuses. Human Rights Watch documented 16 cases in which Houthi authorities held people unlawfully, in large part to extort money from relatives or to exchange them for people held by opposing forces. Hostage-taking is a serious violation of the laws of war and a war crime. The United Nations Human Rights Council should renew the mandate of the Group of Eminent Experts on Yemen, which has a mandate to investigate and identify those responsible for abuses.
