An Iranian film, "A Separation," has bagged this year's BBC Four World Cinema Awards.

The story is about the break-up of an Iranian marriage, where the estranged middle-class couple, Simin and Nader, appear in the court. Simin wants divorce and the custody of their daughter, while Nader employs a lower-class woman, Razieh, to take care of his Alzheimer's-ridden father. Amid a series of events which take place, Nader is charged with a serious crime.

The film has been chosen from five shortlisted entries by a panel of judges including film director David Hare, documentary film-maker Gurinder Chadha, Oscar-winning documentary producer John Battsek and Booker Prize-winning author Kazuo Ishiguro.

Executive producer Negar Eskandarfar said he was glad that film was "welcomed internationally" while receiving the award in London, a BBC report has said.

French actress, Isabelle Huppert, won the world cinema achievement award. According to the BBC, the actress, who is popular for her portrayal in 2001 film, "The Piano Teacher," said she was "deeply touched" to receive the award.

However, director of the film Asghar Farhadi was unable to attend the event.
