Lost in translation: International comics in Edinburgh

Edinburgh Fringe Festival is the world's largest arts festival and attracts artists and visitors from around the globe.

Comedy is big business and a successful Edinburgh run can make a comedian's name.

It is vital to connect audiences and reviewers to get noticed amid fierce competition.

International artists have the additional hurdle to clear - the language barrier.

BBC World visited the fringe and spoke to comics from across the globe to see if comedy is lingua franca.
