Amnesty International is seriously concerned for the safety of Mario de Jesús Castañeda, a leader of the Huila branch of the Colombian Trade Union Confederation (Central Unitaria de Trabajadores, CUT), following a recent death threat against him. On 22 September, a letter addressed to Mario Jesús Castañeda was sent to the CUT offices in Neiva, Huila department. The typed letter was signed by the Bolívar Central Bloc (Bloque Central Bolívar), of the United Self-Defence Forces of Colombia (Autodefensas Unidas de Colombia, AUC)
