No consensus on security measures

The US is stepping up security by heightening the screening of passengers, flying into the country after a failed bomb plot on Christmas Day. In-bound passengers from 14 nations such as Nigeria and Yemen will face enhanced screening procedures. But there is no consensus among European countries on improving security measures.

The enhanced screening techniques include full-body pat-downs, carry-on bag searches, full-body scanning and the use of explosive detection technology.

Anyone traveling from or through nations regarded by Washington as state sponsors of terrorism - as well as what are referred to as "other countries of interest" - will be required to go through such procedures.
