The president of Colombia, Gustavo Petro, and the Minister of Defense, Ivan Velasquez, ask for forgiveness from the families of people who were forcibly disappeared and killed, during a ceremony in Bogota.

On the same day, Colombia’s Army also apologized for the deaths of civilians executed by soldiers. IMAGES AND SOUNDBITES
