Wearing black jackets adorned with a symbol of a Viking and the Finnish flag, the "Soldiers of Odin" have surfaced as self-proclaimed patriots patrolling the streets to protect native Finns from immigrants, worrying the government and police.
On the northern fringes of Europe, Finland has little history of welcoming large numbers of refugees, unlike neighbouring Sweden. But as with other European countries, it is now struggling with a huge increase in asylum seekers and the authorities are wary of any anti-immigrant vigilantism.
A group of young men founded Soldiers of Odin, named after a Norse god, late last year in the northern town of Kemi. This lies near the border community of Tornio, which has become an entry point for migrants arriving from Sweden.
