Hollywood star Angelina Jolie called Bosnia's decision to include prevention of sexual violence in military training "inspiring" and "groundbreaking".
Speaking at a conference in the Bosnian capital Sarajevo, the UNHCR goodwill ambassador said the issue of war zone rape "has been a taboo subject in all countries".
"You are helping to break down those taboos and [are] redefining soldiering in the 21st Century," she told the audience.
"There can be no peace in conflict or post-conflict zones while women are raped with impunity," the actress added.
Actress Angelina Jolie, in her role as UNHCR goodwill ambassador, and Foreign Secretary William Hague met Bosnia's presidency to discuss the prevention of sexual violence in conflict.
