Home Secretary Theresa May has condemned “all forms of extremism” as she praised a British-based Islamic group for its commitment to peaceful co-existence and charitable works. Mrs May said there had been an increase in attacks directed against Muslim communities since the “horrendous” murder of Drummer Lee Rigby in Woolwich last month. Mrs May was speaking at an event in the House of Commons marking the centenary of the establishment of the Ahmadiyya Muslim Community in the UK. The branch of Islam was founded in the late 19th century in India, but its leader has been based in Britain since 1984 as a result of persecution in Pakistan, where they are officially declared non-Muslims. Mrs May said the Ahmadiyya were subjected to persecution in Pakistan and threats in the UK.
