Liam Cunningham said the refugee crisis "is a man-made" situation
Stars from Game of Thrones are calling on EU leaders to do more to help the tens of thousands of refugees stranded in Greece.
Lena Headey, Maisie Williams and Liam Cunningham visited refugee camps in Greece just after they finished filming the last series.
They have asked the European Union to reconsider its agreement with Turkey - which forces migrants to apply for asylum there before they can travel to the EU.
Headey - who plays Cersei Lannister in the show - says the visit was "life changing".
"We can do better for them. We must do better for them," the actress said.
Irish actor Liam Cunningham - who has starred as Davos Seaworth since the second season of the fantasy show - said: "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?" he added.
The three actors visited Greece with the International Rescue Committee (IRC).
Panos Navrozidis, country director with IRC Greece, explained: “The truth about this crisis is that there are options for the family members Lena, Maisie and Liam met in Greece.
"There is no reason why 57,000 people should be forced to put their lives on hold.”
