Authorities in Spain suspect the men had been in contact with "at least one" of two alleged Islamic State extremists arrested in Salzburg, Austria shortly after the attacks in Paris in November 2015 that killed 130 people, the interior ministry said.
Varasiestādes uzskata, ka aizturētie vīrieši kontaktējušies arī ar vienu no ekstrēmistiem, kas neilgi pēc 2015.gada novembrī notikušajiem teroraktiem Parīzē tika aizturēti Austrijā.
