'The film has some sentences which were very offensive towards one of Afghanistan's ethnicities, namely the Hazara. For this reason it has been banned,' Najib Manalai, Afghanistan's minister of culture adviser, said in an official statement.
The film starring Indian stars Arshad Warsi and John Abraham is a socio-political comment on the war ravaged country.
While filming it, director Khan and both the actors received life threats from the Afghan rebels.
However, Khan shot the film on location under heavy security. He wrapped it up in 45 days.
The film, based on Khan's personal experience in the country while filming a documentary film, hit the screens in India on 15th December and received critical acclaim.
