Terrorist combatants have attempted to enter Finland, reports the newspaper Helsingin Sanomat. The head of the Finnish Security Intelligence Service (Supo) told the national daily that individuals have also left Finland to join armed training and combat.
The risk of a terrorist attack in Finland has, however, not risen, according to Supo head Antti Pelttari.
With a handful of people leaving Finland to engage in fighting or training, the number is far lower than that in other Nordic countries. He also notes that terrorist training is not a crime in Finland as it is in many other European states.
