Many Iranians are boycotting the World Cup as they feel the team has not done enough to support the protest movement or criticise a regime which has killed hundreds of people. But a group of expat fans are trying to keep the protest flame alive inside Qatar's stadiums.

"I'm happy I'm here and that I'm doing this because I could see the fear in their eyes," says Tara, a young Iranian woman and football enthusiast. 

She tells me the World Cup stadiums are heavy with government supporters for Iran's matches.

Tara is not her real name. Everyone I spoke to would only agree to an interview if they could keep their identities secret.
