Women and girls are bearing the brunt of extremists that revel in treating them barbarically.

She concluded her speech by stating that the solution needs to be tailored to, and pioneered by, women themselves. "We need policies for long-term security that are designed by women, focused on women, executed by women - not at the expense of men, or instead of men, but alongside and with men," she said."There is no greater pillar of stability than a strong, free and educated woman, and there is no more inspiring role model than a man who respects and cherishes women and champions their leadership," she added.She joined former British foreign minister William Hague, Senegalese activist Bineta Diop and Zainab Bangura, who is the UN's Special Representative on Sexual Violence in Conflict, on the panel at the event.
