Cameron condemns David Haines\\\'s \\\'evil murder\\\'

The murder of David Haines was an ‘act of pure evil’, British Prime Minister David Cameron has said after the release of a video purporting to show the UK hostage’s beheading. The PM vowed to do ‘everything in our power to hunt down’ the aid worker’s killers. Haines’s family said the 44-year-old would be ‘missed terribly’. Islamic State militants have already beheaded two Americans, saying it was in response to US air strikes in Iraq. The latest video also includes a threat to kill a second British hostage. Haines, a father-of-two from Perth, was kidnapped in Syria in March 2013. In a statement released by the Foreign Office, Mike Haines said his brother ‘was and is loved by all his family and will be missed terribly’, according to BBC.
