A British newspaper received a mystery call minutes before the assassination of John F Kennedy.

This is one of the most astonishing revelations from the JFK files, released on Thursday.

The revelation was made in papers relating to the killing, which happened on November 22 1963.

A memo to the director of FBI revealed that a call was made to the senior reporter at the Cambridge News at 6.05pm on the day Kennedy was shot in Dallas, Texas.

The document, from deputy director James Angleton, said: "The British Security Service (MI-5) has reported that at 1805GMT on 22 November an anonymous telephone call was made in Cambridge, England, to the senior reporter of the Cambridge News.

"The caller said only that the Cambridge News reporter should call the American Embassy in London for some big news and then hung up."
