Which international law governs the treatment of prisoners of war?

The Geneva Conventions govern the treatment of prisoners of war, establishing the standards of international law for humanitarian treatment. Specifically, these treaties, which were first adopted in 1864 and have been updated several times, outline the rights of captured military personnel and provide protections for their humane treatment. They mandate that prisoners of war should be treated humanely, provided with adequate food and medical care, and protected from violence and intimidation.

The Geneva Conventions form the foundation of international humanitarian law applicable to armed conflict and ensure that even amid warfare, respect for human dignity is upheld. This legal framework is critical not just for the rights of prisoners but also sets obligations for their captors, emphasizing the importance of humane treatment regardless of circumstances.

While the other options mentioned pertain to human rights or specific populations, the Geneva Conventions stand uniquely focused on the welfare and rights of individuals captured during armed conflicts, making them the correct choice for the treatment of prisoners of war.
