The Kimberley Process Certifications Scheme (KPCS) sets standards for lawful and ethical mining of diamonds, too often linked to conflict and bloodshed. Zimbabwe has failed to comply with the KPCS's regulations. Instead, Zimbabwe has continued to send its military troops to the diamond fields of Marange, creating illicit patterns of access to the precious gems. Human Rights Watch reports ongoing human rights abuses (killings, beatings, torture), smuggling, and threats against witnesses to abuse. Threats have proven so severe that one witness, who Human Rights Watch reports provided evidence to a Kimberley Process review mission, was forced into hiding for fear of losing his home - or his life.
