The UN investigation found the FARC in violation of several principles of international humanitarian law, including an indiscriminate attack causing unnecessary civilian casualties, failure to distinguish between civilian and combatant, failure to take efforts to protect civilians from avoidable harm, and attacks against cultural property. Prohibitions against these acts are found in Common Article 3 of the 1949 Geneva Conventions and Articles 4, 13, and 16 of Additional Protocol II. The UN also considered the FARC responsible for the forced displacement of civilians generated as a consequence of the attack on the church, placing the act in violation of Article 17 of Protocol II.
