Sophie Turner, Maisie Williams appear in campaign spotlighting the plight of refugees

NEW YORK, March 14 (UPI) -- Cast members from HBO's Game of Thrones are taking part in the International Rescue Committee's campaign to bring attention to the global refugee crisis.

Announced as the fifth anniversary of the Syrian civil war is marked, the campaign is also intended to raise emergency funds to help rescue the millions of people displaced by conflict and natural disaster.

The "Rescue Has No Boundaries" public-service announcements feature GOT stars Lena Headey, Sophie Turner, Maisie Williams, Nikolaj Coster-Waldau, Liam Cunningham, DeObia Oparei, John Bradley, Tom Wlaschiha, Eugene Simon and Oona Chaplin.

"We are currently facing the worst humanitarian crisis since World War II," David Miliband, president and CEO of the International Rescue Committee, said in a statement Monday. "Our partnership with HBO and Game of Thrones -- which premiered around the same time the war in Syria began -- hopes to galvanize the general public to take action and rise up for refugees."

"Our longstanding support of the IRC comes from a deep respect for the humanitarian work they do and a fundamental understanding of their mission to get much needed relief to millions of refugees displaced throughout the world," added Richard Plepler, chairman and CEO of HBO. "On behalf of the HBO employees and talent associated with Game of Thrones, who graciously donated their time and resources to this effort, we are honored to join the IRC in this partnership at a time of great need around the world."
