Finland builds security fence on Russian border to address migration and security concerns.

Finland has begun construction of a barbed-wire fence along its border with Russia to curb illegal migration. The fence will be three meters high and extend up to 200 kilometers. The project is estimated to cost $422 million and is scheduled to be completed by 2026. The main purpose of the fence is to prevent illegal immigration from Russia and give reaction time to authorities. The move was prompted by Russia's invasion of Ukraine in 2014, which led to Finland's quick push to join NATO after decades of military nonalignment.
