KADUNA Nigeria (Reuters) - In classrooms facing a sandy courtyard in the northern Nigerian city of Kaduna, Maska Road Islamic School teaches a creed that condemns the violent ideology of groups like Boko Haram.
Not everyone has got its message. Umar Farouk Abdulmutallab, known as the "Pants Bomber", spent his youth in this school - and ended up trying unsuccessfully to blow up a U.S. airliner on Christmas Day 2009 with explosives hidden in his underwear.
