Security screeners at Denver International Airport have begun swabbing the hands and belongings of some passengers to check for explosives.
The airport started the screening of passengers at random this week as part of a new security measure also being used at airports around the country.
The National Security Administration says the screening is a response to a Nigerian man's alleged attempt to blow up a Detroit-bound Northwest Airlines plane on Christmas Day with an explosive-laden device hidden in his underwear.
Airline passengers are chosen at random at security checkpoints to have their hands and carry-on baggage swabbed. The swab is then scanned through a machine to check for explosive residue.
