Via the Telegraph:
A new report shows that the success of anti-radicalisation measures in many of Britain's mosques has pushed militants underground, making them harder to detect by both community leaders and police.
Feeding the process are jailed militants, such as Abu Hamza, who is still exerting an influence from his prison cell on impressionable Muslim youngsters susceptible to his violently anti-Western rhetoric.
Details of the report emerged ahead of imminent release of a key government review of its counter-terrorism strategy, expected this month.
