A radical Islamist said to have mentored a Muslim suicide bomber is teaching and preaching at a top British university

British-born Reza Pankhurst is allegedly spreading the message of hard line group Hizb ut-Tahrir at the London School of Economics. The public school-educated 34-year-old is said to have been a major influence on Omar Sharif, who took part in a suicide bomb attack in Israel in 2003. Hizb ut-Tahrir campaigns for Muslims to unite and control the world, and has been accused of anti-Semitism. Pankhurst was jailed for three years in Egypt for promoting the banned organization in 2004
