Anyone who, in connection with an international or non-international armed conflict, … carries out an attack against personnel, installations, material, units or vehicles involved in a humanitarian assistance or peacekeeping mission in accordance with the Charter of the United Nations, as long as they are entitled to the protection given to civilians or civilian objects under international humanitarian law, shall be liable to imprisonment for not less than three years. In less serious cases, particularly where the attack is not carried out with military means, the period of imprisonment shall be for not less than one year.
