Game of Thrones stars Lena Headey, Maisie Williams and Liam Cunningham appealed to European Union leaders this week to do more for the approximately 57,000 refugees of the ongoing Syrian civil war who are currently stranded in Greece. The appeal came during a visit to operations of the International Rescue Committee programs in Greece and followed meetings earlier this week with refugees affected by the March deal between the EU and Turkey. The visit included trips to the island of Lesbos, where Headey met with a young Syrian woman traveling alone with three children under the age of 11, to Cherso in Northern Greece, where Williams met a young aspiring actor from Syria, who wants nothing more than the chance to live out her dreams in safety. Cunningham meanwhile met with Afghan and Syrian fathers who talked about their reasons for leaving their countries and what life is like for them as refugees.

“These smart, hardworking people want to go home. They want to return to their communities and to their neighborhoods,” said Headey in a statement. “They want their children to continue their education. They want to continue their university and they are stuck. They’re stuck. And they’re unbelievably sad. Understandably. We can do better for them. We must do better for them.”

“For me it is about the children… children with so much potential, so many hopes and dreams,” Williams said. “Where is the humanity that makes it acceptable for them to languish in refugee camps – in Europe?”

Added Cunningham, “This is not an earthquake, this is not a tidal wave. This is a man-made crisis. 57,000 stranded in Greece. Refugee camps in Europe? Is this truly the standard EU leaders want to set as the way to respond to the global refugee crisis?”

Game of Thrones recently completed its sixth season, with Headey, who plays Cersei Lannister, Cunningham, who plays Ser Davos, and Williams, who plays Arya Stark, all set to return for season 7, expected to premiere in April of 2017.
