Alalam Europe
A ministry statement said the four had links with the so-called "Syrian refugee route" that ISIL (ISIS / IS / Daesh ) is thought to have used to get the Paris attackers to Europe via the Greek island of Leros in October 2015, the Daily Star reported.
Police believe the four arrested Monday had contacts with two extremists arrested in Salzburg, Austria, shortly after the November 2015 attacks.
Two were arrested in towns in northwestern Spain and two others in the Southeastern city of Almeria.
No details on their identities were released.
