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

Finland has started building a barbed-wire fence along its border with Russia to curb illegal migration. The fence is primarily meant to prevent illegal immigration from Russia and give reaction time to authorities. The move comes less than two weeks after Finland joined NATO as the 31st member of the military alliance. The border fence project is estimated to cost a total of 380 million euros ($422 million) and is scheduled to be completed by 2026.
