The International Rescue Committee (IRC) has teamed up with HBO's Game of Thrones to launch the Rescue Has No Boundaries campaign to bring attention to the global refugee crisis, and raise emergency funds to help rescue the millions of people displaced by conflict and natural disaster.

The initiative, led by Emmy-winning actress Lena Headey - along with other Game of Thrones cast members, including Sophie Turner, Maisie Williams, Nikolaj Coster-Waldau, Liam Cunningham, DeObia Oparei, Tom Wlaschiha, Eugene Simon and Oona Chaplin - urges that 'the time is now to rescue refugees no matter where they are in the world'.
