David Haines's killer issues threats to David Cameron - audio

Audio from a new video released by the militant group Islamic State (Isis), which appears to show the beheading of British hostage David Haines. In the clip, the Isis militant warns British prime minister David Cameron against arming peshmerga forces in Iraq and supporting American-sanctioned air strikes. The masked man calls Cameron an 'obedient lapdog', and says further actions against Isis will only 'accelerate your destruction'
