Practice Relating to Rule 11. Indiscriminate Attacks
Zimbabwe’s Geneva Conventions Act (1981), as amended in 1996, punishes “any person, whatever his nationality, who, whether in or outside Zimbabwe, commits any such grave breach of … [the 1977 Additional Protocol I]”. 
Zimbabwe, Geneva Conventions Act, 1981, as amended in 1996, Section 3(1).
The Report on the Practice of Zimbabwe considers that the question of indiscriminate attacks is problematic since much depends on the objective in question, on necessity and on the military advantage to be gained. According to the report, the principle of proportionality, however, remains applicable.
