Graffiti artists dupe Homeland with anti-show graffiti on set walls

Graffiti artists hired to work on the set of TV show Homeland have duped the popular series, painting Arabic slogans criticising it on walls seen in the background.
In one episode set in a Hezbollah-run refugee camp in Lebanon but filmed in Berlin, star Claire Danes can be seen walking by slogans including āHomeland is racistā and āHomeland is a joke and it didnāt make us laughā.
