The present report focuses on the mass casualties of refugees and migrants in the course of their flight. It addresses killings by both State and non -State actors, and denounces a quasi-generalized regime of impunity, worsened by an absence of accurate data on the dead and missing. The Special Rapporteur of the Human Rights Council on extrajudicial, summary or arbitrary killings calls urgently on States to address this human rights crisis by prioritizing the protection of the right to life in their migration and refugee policies.
