Cameron: Britain must be permanently vigilant

Britain had no intelligence of an imminent attack on its soil but the country remain \"permanently vigilant\" in the wake of an attack on a shopping mall in Nairobi, Kenya, in which six Britons were killed, prime minister David Cameron said Sunday. He warned there was a fear of British-based, Al-Shabab-trained Somalis committing outrages on British soil. Speaking to the BBC, Cameron said the British security bodies were \"looking at this for a long time because of the appalling attack that happened in Mumbai in India.\" Cameron chaired a meeting of the government\'s emergency committee, Cobra, on Monday to discuss the three-day siege, which ended on Tuesday. \"I have personally chaired a whole series of meetings years ago, but again actually this week, to check that we have got everything in place to prepare for those sorts of attacks. \"We don\'t have intelligence that something is about to happen, but it pays to be very, very prepared, very, very cautious, and to work out we have everything in place we can to deal with awful events like this,\" he said. Cameron called on importance of fighting terrorism and extremism in Britain, Africa, Afghanistan or Pakistan. \"It goes to this whole argument about why we need well-funded intelligence service, why we need to be engaged in the world, we need to share intelligence with others and why we have to be permanently vigilant,\" he added
