The actress and human rights activist spoke of the harrowing moment she met girls as young as seven who had been brutally raped in war zones.

Jolie, who is giving evidence to a Lords committee, said terrorist fanatics in the ‘most aggressive terrorist group in the world’ were using sex attacks as a ‘very effective weapon.’

She said the use of rape by ISIS as a ‘policy’ was a new horror that the world had not seen before and urged a ‘very, very strong response’ to the terror group in Iraq and Syria.

As the extraordinary hearing got underway, it emerged that Jolie had given members of the committee copies of her film “In the Land of Blood and Honey.”

Jolie, who is a long-standing campaigner on the issue, is appearing alongside former Foreign Secretary William Hague.

The pair hosted an ‘End Sexual Violence in Conflict’ summit in London in June last year which brought together diplomats, officials and non-profit representatives from more than 100 countries to press for the rights of victims of sexual violence — women, men and children alike.

The global star told peers: “I think the most important thing to understand is what it’s not. It’s not sexual, it is a violent brutal terrorizing weapon.”
