Eight British and American Shi'ite Muslims who said they were arrested and tortured by religious police as they prayed during a pilgrimage to Saudi Arabia called Friday for a full inquiry into their ordeal. The group, some of Iraqi descent and aged between 16 and 26, told a London news conference they had been detained and beaten by police during their visit to holy city of Mecca. Saudi Arabia's embassy in London was not immediately available to comment on the allegations.
