The apparent ties between the Nigerian man charged with plotting to blow up an airliner on Christmas Day and a radical American-born Yemeni imam have cast a spotlight on a world of charismatic clerics who wield their Internet celebrity to indoctrinate young Muslims with extremist ideology and recruit them for Al Qaeda, American officials and counterterrorism specialists said.American military and law enforcement authorities said Thursday that the man accused in the bombing attempt, Umar Farouk Abdulmutallab, most likely had contacts with the cleric, Anwar al-Awlaki, whom investigators have also named as having exchanged e-mail messages with Maj. Nidal Malik Hasan, an American Army psychiatrist charged with killing 13 people in a shooting rampage in November at Fort Hood, Tex.
