Angelina Jolie claims working with survivors of rape was an ''honour''.

The 'Maleficent' actress, who is a special envoy for the UN Refugee Agency, is determined to help end sexual violence as an act of war.

She said: ''Working on the Preventing Sexual Violence Initiative [PSVI] and with survivors of rape is an honour in itself. I know that succeeding in our goals will take a lifetime and I am dedicated to it for all of mine.

''We all know how hard it is to secure convictions for rape, even in stable democratic countries. So we have to work even harder to make justice possible in fragile countries. And that is the purpose of this protocol.

''It is an essential document and I am so grateful to the hundreds of experts and survivors who have played their part in drafting it.''

Angelina, 39, who has raises Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and five-year-old twins Knox and Vivienne with fiancé Brad Pitt - also claims her humanitarian work has helped her in her own life.

She told HELLO! Magazine: ''It was my work with the UN that made me feel ready to have a family. But as a mother I do often think of how I would feel when I see children and other women in those terrible situations.''
