Ten Swedish airports will introduce a new method of checking for explosives at check-in queues to enhance security screening.
The enhancement in the security screening is a part of the country implementing updated European Union security regulations, reported The Local, and comes in the wake of the recent terror attacks in Paris and Copenhagen.
The new security measure will comply with related regulations issued by the Swedish Transport Agency, the oversight authority for security issues at Swedish airports.
Random checks will be carried out on passengers' hand baggage by using explosive trace detector (ETD), already in use at airports in the UK and US.
The process uses a small cloth to wipe across both bags and clothing. The sample collected by the cloth can then be analysed by a nearby computer designed to trace explosives.
Security manager for Swedavia Anders Lennermark was quoted by The Local as saying: "The technique is so sensitive that even the slightest traces of explosives can be detected."
The state-owned group Swedavia runs the ten airports: Åre Östersund Airport, Gothenburg-Landvetter Airport, Kiruna Airport, Luleå Airport, Malmö Airport, Ronneby Airport, Stockholm-Arlanda Airport, Stockholm-Bromma Airport, Umeå Airport and Visby Airport.
Reportedly, around 33.5 million passengers used Swedavia's airports in 2013.
Sweden came in for a criticism recently for failing to introduce a digital database to help airlines share passenger lists with police, despite EU regulations dating back to 2004 asking airports to provide automatic transfer of customer information.
