U.S. Homeland Security Secretary Janet Napolitano is seeking to allay concerns in some European Union countries over the use of body scanners in airports, saying that as the technology develops they will be less intrusive.

Napolitano says “some of the privacy issues that have been raised are dealt with effectively by the new iterations of the technology.”

Speaking after meeting Thursday with EU interior ministers, Napolitano denied the U.S. was pressuring Europe to deploy the scanners.

But she says better screening technology is crucial to protecting travellers from terrorism.

The U.S. homeland chief says al-Qaeda “is using its best minds against the international aviation system. We must do no less.”
