LONDON (Agencies) - Britain made little progress in reaching out to Muslim communities despite investing considerable time and resources after the 7/7 London bombings in 2005, US diplomats concluded in cables passed to the whistleblowing website WikiLeaks, reports the Guardian. A powerful critique of the governments efforts to engage with British Muslims, outlined in a cable published as police investigate the UK connections of the Stockholm suicide bomber, shows the US embassy in London concluded that both sides often appeared far apart. Since 7/7, HMG has invested considerable time and resources in engaging the British Muslim community, a diplomat at the US embassy in London wrote in August 2006 after the failed liquid bomb plot to blow up transatlantic airliners. The current tensions demonstrate just how little progress has been made. US fears that Britain was struggling to deal with extremism, outlined a year after the 7/7 bombings, are highlighted as police continued to search a house in Luton as part of an investigation into Taimour Abdulwahab al-Abdaly. The challenge of confronting extremists is highlighted in US embassy cables which warned of British Somalis returning to the UK after indulging in jihadi tourism. In a cable on December 2, 2009, a diplomat at the US embassy in Nairobi wrote: There is believed to be a certain amount of so-called 'jihadi tourism to southern Somalia by UK citizens of Somali ethnicity. The threat from Somalia is compounded by the fact that within East Africa there is a lack of local government recognition of the terrorist threat. Separate cables published by WikiLeaks show that prominent British Muslims were highly critical of initiatives introduced by the British government in response to the 7/7 bombings. One cable reports that Sadiq Khan, who is now shadow justice secretary, criticised a programme introduced by the last government. In the cable sent on August 14, 2006, a year after his election to parliament, the diplomat wrote: Labour MP Sadiq Khan said the community feels 'let down by HMG efforts to date, particularly the 'Preventing Extremism Together task forces, which the Home Office created after the 7/7 attacks. Very few of the 64 measures recommended by Muslim leaders on the task force have been implemented, Khan said, creating an 'air of despondency and leading the community to believe that the entire exercise was just a publicity stunt. Khan was one of a series of prominent Muslims who felt so uneasy that they wrote to Tony Blair on August 12, 2006 warning the debacle of Iraq provided ammunition to extremists who threaten everyone, according to the cable. Khan maintains that the letter was prompted by the war in Lebanon. At the time he was highly critical of Tony Blairs reluctance to criticise Israel. The diplomat claimed that the letter, signed by Khan and his fellow Labour MP Shahid Malik, was prompted by the frustration prominent Muslims felt after the bruising their community had taken after 24 UK-born Muslims were arrested in response to the failed liquid bomb plot. The same diplomat wrote: The Muslim communitys reaction to the arrests of 24 of its own sons a kneejerk reaction blaming HMG shows that its leaders too have far to go That said, the Muslim community is not the only element in Britain blaming HMGs foreign policy for inciting radical elements; the left in particular but even the mainstream press has expressed the belief, reportedly widespread, that homegrown terrorism is an 'inevitable response to the UKs involvement in Iraq and reluctance to call for an 'immediate ceasefire in the Middle East. HMGs rather heated response to the letter is undoubtedly aimed at swaying broader opinion. Cables published by WikiLeaks also show the US embassy in London drew up its own programme to win over Muslims.
