The person behind the mail bombs recovered in Britain and Dubai is believed to be the same suspect behind the attempted Christmas Day bombing over Detroit and the explosives that severely injured the Saudi counterterrorism chief in the summer of 2009, U.S. and Yemeni officials tell Fox News. The presumed bomb maker, Ibrahim Hassan al-Asiri, is a Saudi who is on the kingdom's most wanted list. Al-Asiri is believed to be hiding in Yemen and working with U.S.-born cleric Anwar al-Awlaki, making up the leadership of Al Qaeda in the Arabian Peninsula.
