Modern war is often not about soldier against soldier, but a struggle to 'break the will of civilians — women, girls, men and boys' by whatever means possible - including rape - the UN Population Fund (UNFPA) State of the World Population 2010 report published on 20 October states. The term gender-based violence is often used to refer to violence against women, but, as the UN Guidelines for Gender-based Violence Interventions in Humanitarian Settings state, 'it is important to note... men and boys may also be victims of gender-based violence, especially sexual violence'.
