Practice Relating to Rule 22. The Principle of Precautions against the Effects of Attacks
Section A. Precautions to protect the civilian population, civilians and civilian objects
Nigeria’s Military Manual (1994) states: “Similar to attack is the fact that defence measures which may affect civilian persons shall be announced in advance.”
According to the Report on the Practice of Nigeria, although no practice exists regarding precautions against the effects of attacks, the duty to take such precautions is a part of customary international law.
