Angelina Jolie spoke before British parliament Tuesday expressing her concern over ISIS' use of sexual violence.

The actress gave an update on the progress the Sexual Violence in Conflict Committee has made, and said ISIS is rape against women and children "in a way we've never seen before."

The actress and human rights ambassador appeared at the House of Lords committee alongside former foreign secretary William Hague to discuss their Preventing Sexual Violence Initiative, which the pair launched three years ago.

"The most aggressive terrorist group in the world today knows what we know; knows that it is a very effective weapon and are using it as a centerpoint of their terror and their way of destroying communities and families and attacking, destroying and dehumanizing," she told the House of Lords committee, according to the Guardian.

"This is what is beyond something we have seen before. This is actually put into their policy," she said. "They are saying: 'we should do this, this is the right way to build a society, so we tell you to rape.'"

Jolie recalled meeting a 13-year-old Iraqi girl who had, along with her friends, been repeatedly raped.

"The most important thing is to understand what it’s not: it’s not sexual, it’s a violent, brutal, terrorizing weapon and it is used unfortunately, everywhere," she said.
