London Mayor Boris Johnson has hit out at the 'human rights ' group who claimed Britain was to blame for Jihadi John 's murderous actions . He tore into controversial campaigner Asim Qureshi today branding suggestions UK authorities caused the ISIS killer 's radicalisation '100 % the wrong way up ' . The outspoken mayor then added : 'If you 're a human rights group then you should be sticking up for the human rights of those who are being beheaded in Syria and northern Iraq . ' Scroll down for video . London mayor Boris Johnson today hit back at the group who have blamed the radicalisation of Jihadi John on British security services . Mr Johnson ( left ) slammed prisoners ' rights group Cage after the group 's leader Asim Qureshi ( right ) called into his radio show and claimed security services may have made Jihadi John feel unwelcome in the UK . Prisoners rights group Cage held a press conference in which they called Mohammed Emwazi - unmasked as Jihadi John last week - ' a beautiful man ' who was 'harassed ' by British security services . After widespread condemnation of the group and their comments , the London Mayor took on Qureshi , the group 's leader , today . Qureshi called into Mr Johnson 's radio show on London 's LBC radio this morning , claiming his defence of Emwazi had been 'unfairly represented ' . But Mr Johnson refused to go back on his previous criticism of the group and slammed Mr Qureshi 's claims . The Tory mayor said : ' I really , really think that the focus of your indignation and outrage should be at people who go out and join groups that throw gays off cliffs , that behead people who do n't subscribe to their version of Islam , that glorify in the execution of innocent journalists and aid workers . 'They should be the object of your wrath , not the security services who are trying to keep us safe . ' Families of the victims of ISIS killer Jihadi John ( pictured ) - unmasked last week as west Londoner Mohammed Emwazi - have also slammed Cage 's comments , branding Emwazi ' a monster ' Mr Johnson said the group 's claims sent out the completely wrong message , adding : 'If you 're going to have an impact on the lives of young Muslims you have to focus on what these people are doing wrong and not instantly scatter blame around . ' But Mr Kureshi refused to change his line and replied : 'What we want is to understand whether or not , the security agencies , their actions led to [ Emwasi ] feeling that he did not belong to UK society . ' Mr Johnson , who looked furious on a video of the broadcast filmed in the studio , replied : ' I just feel that you 've got it 100 % the wrong way up . You need to see this thing differently . 'The security services are trying to keep is safe . They can not conceivably be blamed for their actions trying to prevent people from committing such atrocities . ' Qureshi 's group press conference last week was broadcast live for 52 minutes on the BBC and 58 on Sky News , with Qureshi speaking uninterrupted for 18 minutes . Mr Johnson is the latest politician to hit out at the perceived apologists for ISIS killers . In a statement to the Commons yesterday , Home Secretary Theresa May said : ‘ I condemn anyone who attempts to excuse that barbarism in the way that has been done by Cage. ’ The row came after a shocking press conference last week , at which Cage said Jihadi John was 'beautiful ' And Jacqui Smith , a Labour former Home Secretary , added : ‘ We can – and should – dismiss the outrageous apologists of Cage who claimed that Emwazi was just a good lad radicalised by the actions of western authorities. ’ Families of the victim 's of Jihadi John 's killing spree have also attacked Cage 's defence of the murderer . Reg Henning , brother of British aid worker Alan Henning who died at the ISIS executioner 's hands , said : 'If he 's a `` beautiful , kind man '' , why is he killing innocent civilians ? 'He 's a monster . Everyone should be doing everything they can to capture him and bring him to justice - not stick up for him like he 's been hard done by . ' Qureshi previously urged protestors at a protest outside the US embassy to 'support the jihad of our brothers and sisters ' in Iraq , Afghanistan , Palestine and Chechnya ' . Speaking through a microphone at the 2006 pan-Islamic Hizb ut-Tahrir movement rally , he said : 'When we see the example of our brothers and sisters fighting in Chechnya , Iraq , Palestine , Kashmir , Afghanistan , then we know where the example lies . Cage 's comments last week has sparked a charity commission investigation into organisations , including the Joseph Rowntree trust and Body Shop founder Anita Roddick 's Roddick Foundation , who fund the group . Qureshi appeared at a protest in 2006 at which he said Muslims were being oppressed by the West and called for support for jihad , shouting : 'Allahu Akhbar ! Allahu Akhbar ! '
'Human rights ' group sparked outrage claiming ISIS killer was 'beautiful ' They have since blamed British security services for his radicalisation . But Theresa May today took on the group 's leader on radio phone-in . London mayor said groups ' approach was '100 % the wrong way up '
