Ibrahim Hassan al-Asiri is the man U.S. authorities believe is behind the latest bomb plot from al-Qaida's arm in Yemen. A former chemistry major dropout, Asiri was radicalized in a Saudi prison after he was arrested for trying to get to Iraq to fight the United States.

Dina Temple-Raston talks to Audie Cornish about the bomb-maker.
