Canada wildfires: Yellowknife evacuates

As wildfire roars towards the small city of Yellowknife, the capital of Canada's North-West territories, all the residents have been ordered to evacuate. Also in the programme: Pakistani authorities ban public gatherings in the city of Jaranwala after at least four churches are torched by a Muslim mob. A senior bishop tells Newshour the inciters need to be punished; and we hear from one of the researchers behind a major Hong Kong study showing that an anti-inflammatory drug can boost the effectiveness of emergency contraception.
