Calls to tackle online abuse against Muslims

The police are failing to investigate hundreds of cases of anti-Muslim hate messages on the internet, according to a government-funded monitoring group.
Tell Mama, which records anti-Muslim attacks, said that it recorded 1,432 cases of abuse in the last 22 months.
Shy, a 25-year-old Muslim woman from the South of England told BBC Radio 5 live Investigates: "They said my head should be chopped off and boiled in pig's fat... It was horrible."
The Association of Chief Police Officers said the huge increase in the reporting of hate material on the internet had presented major new challenges for the police, but they were working to address Tell Mama's concerns.
Please be aware Shy's story contains racist language that some people may find upsetting.
