US prisoners 'radicalised'
US authorities believe as many as three dozen Americans who converted to Islam in prison have travelled to Yemen, possibly to train with al Qaida, according to a Senate report.
The “radicalisation” of the individuals has alarmed US officials, even though no evidence has tied them to terror activities.
Several of the individuals have “dropped off the radar” for weeks at a time and continue to carry US passports, according to a copy of the report seen by reporters.
