The officials warn that al-Qaida and other terror groups "continue to seek innovative ways to conduct attacks and circumvent security procedures."

Dec. 24:

_Abdulmutallab re-enters Nigeria for only one day to board a flight from Lagos to Detroit, via Amsterdam. He walks into Lagos' Murtala Muhammed International Airport. Drawing no undue attention to himself, he checks into his flight to Amsterdam at 8:35 p.m. _ a little more than two hours before takeoff. He checks no luggage and carries only a shoulder bag, as he makes his way through an aging terminal decorated with red and green holiday bunting.
