Practice Relating to Rule 2. Violence Aimed at Spreading Terror among the Civilian Population
Mexico’s Army and Air Force Manual (2009) states that the 1977 Additional Protocol I “contains a special section on the protection of the civilian population, which … , among other things, … prohibits ‘[a]cts or threats of violence the primary purpose of which is to spread terror among the civilian population’”. 
Mexico, Manual de Derecho Internacional Humanitario para el Ejército y la Fuerza Área Mexicanos, Ministry of National Defence, June 2009, § 292.
At the CDDH, Mexico stated that it believed Article 46 of the draft Additional Protocol I (now Article 51) to be so essential that it “cannot be the subject of any reservations whatsoever since these would be inconsistent with the aim and purpose of Protocol I and undermine its basis”.
