Manveen Rana uncovers hate speech, sectarianism and even support for Jihad in some of Britain's Urdu language newspapers, radio stations and TV channels. While we are often told the internet and social media have accelerated the fermentation of extremist ideas, File on 4 reveals how widely-available 'old media' is also disseminating sectarian and anti-Semitic messages, as well as support for Pakistani militant groups, through newspapers and TV channels accessible in Muslim communities across the UK. A common theme is content about the Ahmadiyyah community, who are considered by some Muslims to be heretics. A persecuted community in Pakistan, such violence came to the UK in 2016 when shop keeper Asad Shah was fatally stabbed by a man accusing him of blasphemy. Despite this shocking sectarian murder, British Urdu media continues to publish insulting material targeting the Ahmadiyyah community - included campaigns calling on readers to boycott Ahmadi-made goods. But at what point do these media outlets cross the line from bad taste to criminal behaviour? And are media regulators doing enough to prevent and punish the offenders?
