Swiss parliament wants the police to be able to monitor the movements of suspected terrorists without their knowledge.
The federal police would be allowed to covertly register people who are potentially travelling for the purposes of jihad.
Those registered to trigger such notifications to the authorities, would be people considered to pose a concrete threat to internal or external security.
The police would be notified if a registered person passes through border control and enters the Schengen zone, or if such a person has to show proof of identity to officials while in a Schengen zone country.
The motion, approved by both parliamentary chambers, will now be passed on to the cabinet. This summer the cabinet already requested the justice ministry to draft a bill including this measure, and others, aimed at combating terrorism.
