London • Brad Pitt has joined Angelina Jolie at a London summit on sexual violence, lending the couple's star power to the campaign to end rape in war zones.
The four-day London conference is organized by British Foreign Secretary William Hague and Jolie, a United Nations special envoy.
They hope representatives of the more than 100 countries present will back a new protocol laying out how sexual violence in conflict zones should be investigated and prosecuted. They say they want to end the "culture of impunity" for wartime sex crimes.
Pitt watched from the audience Thursday as Jolie and Hague spoke to delegates at the east London conference venue.
