'His blood is on the hands of the British parliament': Jihadi John's chilling message as he beheads second Briton Alan Henning.

                     

British aid worker Alan Henning (left and inset) has been beheaded by Islamic State militants in Syria, a video posted online by the fanatics has revealed. The Foreign Office has confirmed it is looking into reports of Mr Henning's death, which comes just days after his distraught wife Barbara appealed for his safe return. In the video, which emerged online last night, Mr Henning can be seen on his knees (left) as the British Islamist known as Jihadi John waves a knife at the camera. Before his death, Mr Henning tells the camera: 'I am Alan Henning. Because of our Parliament's decision to attack the Islamic state I as a member of the British public will now pay the price for that decision.' Following the same format as previous videos released by the terrorist group, the footage ends with the Jihadi threatening that the next victim will be Iraq war veteran and U.S. citizen Peter Edward Kassig (right).
