The Islamic State militant group has released a video online showing the beheading of US journalist James Foley, missing since 2012.

In 2012, Foley spoke to the BBC at an auction he had helped organise to raise money for the family of Anton Hammerl, a photographer killed in Libya whilst covering the uprising against Col Muammar Gaddafi in 2011.

In the interview with the BBC's Anna Bressanin, Foley explained what drove him to do his job.
