The correct statement that compares the human rights violations in Cambodia and Rwanda is:
It was difficult to confirm information about violations in Cambodia, while journalists reported on the violations in Rwanda as they were happening.
This highlights the contrast in the situation during the two genocides, where the global awareness and media coverage differed significantly. In Cambodia, the regime operated in secrecy, making it harder to report and verify the extent of the violations, whereas in Rwanda, there was more media presence documenting the atrocities as they unfolded.
