Practice Relating to Rule 42. Works and Installations Containing Dangerous Forces
Benin’s Military Manual (1995) states that it is prohibited:
to attack dykes, nuclear power plants and dams, if such attack would release dangerous forces which may cause severe losses among the civilian population, unless these works have been used in direct support of military operations or for military purposes and an attack on these objectives is the only way to terminate such use.
