We wrote to officials in Colombia to urge investigations into the assassinations of eight social leaders across six departments during the last week of December, bringing the total to an astounding 310 assassinations of social leaders and other human rights defenders during 2020. The victims are: Felipe Guevara Henao- journalist (Dec 23 in Cali, Valle del Cauca Department); Fablio Armando Guanga Quistial- Awá indigenous activist (Dec 23 in Tumaco, Nariño Department); Pedro Alejandro Pérez Doria- town councilor (Dec 24 in San Pelayo, Córdoba Department); Roberto Eduardo Parra Ovalle - peasant farmer and environmental defender (Dec 25 in Mesetas, Meta Department); Juvenal Vitonás Achicué - indigenous community activist (Dec 26 in Toribío, Cauca); Luis Alberto Anay Ruiz – teacher (Dec 27 in Tumaco, Nariño Department); Omar Moreno- agricultural trade unionist (Dec 28, between Llorente and Pasto, Nariño Department); Norbey Antonio Rivera - agricultural trade unionist (Dec 30 in Popayán, Cauca Department). We are urging that authorities in Colombia guarantee thorough investigations to find the perpetrators of the atrocities listed above and provide all necessary security measures for social leaders to ensure full implementation of the provisions of the peace process.
