The TSA is issuing a new warning to airlines about how terrorists might hide explosives. It involves surgically implanting them inside humans.

FOX News Radio's Jared Halpern reports from Washington DC:


From FOX's Catherine Herridge:

 Two sources tell Fox News that the threat information -- that led to the TSA warning --  has the signature of al Qaeda and al Qaeda in the Arabian Peninsula -- this was the ground behind the last two major plots targeting the United States including the underwear bomber on Christmas Day 2009.  Bomb maker Ibrahim al Asiri who was also behind the cargo printer bomb plot last fall -- in both cases Asiri used a non-metallic explosive -- that defies conventional screening procedures -- which led to the controversial pat down policy by the TSA at the airport.
