Author JK Rowling has led condemnation of media mogul Rupert Murdoch after he said all Muslims must take responsibility for jihadist attacks.

The head of News Corps took to Twitter in the wake of the Paris terror atrocities to say even innocent Muslims “must be held responsible” until they destroyed the “jihadist cancer”.

But Harry Potter creator, Ms Rowling hit back asking if as a Christian did that make her responsible for Mr Murdoch.

She also took the blame for the Spanish Inquisition and all Christian fundamentalist violence.

Mr Murdoch was criticised in the wake of the Sydney hostage incident last month in which three people died, including hostage taker Man Haron Monis.

He was accused of being insensitive after sending a tweet congratulating the Australian Daily Telegraph for being the first to report on the “bloody outcome”.

Following the Paris outrages, he tweeted: “Maybe most Moslems peaceful, but until they recognize and destroy their growing jihadist cancer they must be held responsible.”

He then added: “Big jihadist danger looming everywhere from Philippines to Africa to Europe to US. Political correctness makes for denial and hypocrisy.”

But in response, Ms Rowling said: “I was born Christian. If that makes Rupert Murdoch my responsibility, I'll auto-excommunicate.”

She also highlighted a study that concluded eight times more Muslims had been killed by Islamist terrorists than non-Muslims.
