More than three quarters of British jihadists have been involved with non-violent Islamist groups before turning to foreign fighting and carrying out terrorist attacks, a report has indicated.
Islamist groups have acted as a recruitment pool for dozens of jihadists who have gone on to join al-Qaeda, Islamic State and other terrorist groups, according to research by the Tony Blair Institute for Global Change.
Researchers examined the biographies of 113 people from across the UK who had joined the jihadist movement, from the 1980s to the Syrian civil war. The institute's report says that at least 77 per cent of the sample had links to Islamism, either through association with Islamist organisations or by connections to those who spread the extremist ideology.
