Governments will be held to account over ending sexual violence in war zones, Angelina Jolie has said.

The Hollywood actress and UN special envoy said a new international protocol represented the “beginning of the fight” against the practice.

Speaking to the BBC, she said the protocol meant governments in war zones would no longer be able to say they didn’t know how to tackle the issue.

Ms Jolie said women around the world were “united in this fight together”.

The actress and UK Foreign Secretary William Hague have been co-chairing the the End Sexual Violence in Conflict global summit, which brings together representatives from more than 100 countries.
