The Military Manual (2005) of the Netherlands states:
In the history of warfare, reprisals carried out have often exceeded the set limits. This has led to the current prohibition, in the humanitarian law of war and specifically in AP I [1977 Additional Protocol I], of reprisals against several groups of people and objects.
The following are now forbidden as reprisals:
- attacks against the natural environment.
