Six women Nobel Peace laureates are attending a major peace conference in Northern Ireland.
The event, Moving Beyond Militarism and War: Women-driven solutions for a non-violent world, is being launched at Belfast City Hall later.
It continues with a three-day conference at the Culloden Hotel in County Down on 28-30 May.
Northern Ireland's Mairead Maguire is among the Nobel laureates.
Ms Maguire was a co-founder of the Peace People movement in Northern Ireland in the 1970s, and many of the original members will be at the city hall event.
The other laureates are Leymah Gbowee (Liberia), Tawakkol Karman (Yemen), Shirin Ebadi (Iran), Rigoberta Menchu Tum (Guatemala) and Jody Williams (USA).
Some of the world's leading experts in conflict resolution and the impact of war and militarisation on women will also attend.
The conference and related events will focus on strategies for a non-violent world and highlight the work of women peacemakers from around the globe.
The Nobel Women's Initiative has organised the three-day conference.
It is the first time the conference has been held in the UK and will bring together more than 100 women from all over the world who have experienced the horrors of war.
It will cover topics such as building a lasting peace in Northern Ireland and globally, and preventing rape and gender violence in areas of conflict.
