Women and men: United to end violence against women is the theme of this year's International Women's Day which is observed at the United Nations.

Sexual violence, and the threat of violence, increases women's vulnerability to HIV and in certain parts of the world is being used as a tactic of war. UN Secretary-General Ban Ki-moon highlights this in his message marking International Women's Day.

He said: "Violence against women is also linked to the spread of HIV/AIDS. In some countries, as many as one in three women will be beaten, coerced into sex or otherwise abused in her lifetime. Women and girls are also systematically and deliberately subject to rape and sexual violence in war."

UNAIDS executive director Michel Sidibé is also unequivocal on the need to end this violence in his statement: "Violence, including rape and sexual abuse against women and girls should not be tolerated in any circumstances, be it in conflict or war or at home in our own communities." Sexual violence in conflict has not been a high priority for security institutions and is often overlooked due to stigma and under-reporting. However, the trauma and terror of rape can wound as deeply as bullets and in areas with high HIV prevalence, women are also at risk of being infected with HIV.

Leo Kenny, Team Leader of UNAIDS Security and Humanitarian Response is convinced of the pressing need to address the issue sexual violence among the uniformed services: "While soldiers and uniformed service personnel have been perpetuators of violence against women, they have also been part of the solution and are potential key agents of change if the right programmes are put in place."

"Educating and involving peacekeepers in addressing sexual violence is important as soldiers have influence among their peers both within the service and the wider community. By changing their perceptions and behaviours it can positively impact the larger population," added Mr Kenny.
