"What Sakra told officials during his interrogation suggests a deep jihadist career. The Syrian, who knows weapons as well as he knows his whiskey and wine, has obviously played a far more important role in the terrorist underground than officials first suspected. According to his own testimony, he knew about the London bombings before they happened, and supported the pilots on 9/11."
