Angelina Jolie, a Hollywood star, warned on Tuesday that the Islamic State (IS) has been raiding raids in unprecedented levels, and has called for sharper action against those responsible.

Jolie, UN Special Envoy for Refugees and Activists of Sexual Violence in Wars, said she was raped by "politics" and asked for a "very strong response".

IS members have kidnapped, raped and turned into sexual slavery by thousands of women and girls since they declared the caliphate in the vast areas of Syria and Iraq last summer, warned the UN and human rights organizations.

"The most aggressive terrorist group today ... uses racism as the focal point of its terror and the way it destroys communities and families," Jolie said in front of the British Parliament's committee.
