BY A STAFF REPORTER: Finland will close its borders to Russian tourists from Friday midnight local time (5 p.m. ET) until further notice amid a record number of Russians crossing into the country following Moscow's partial mobilization order, the government confirmed Thursday. On September 21, Russian President Vladimir Putin announced the immediate "partial mobilization" of citizens for its war in Ukraine. Since then, there has been an exodus of citizens fleeing the country and thousands of Russians have entered neighboring Finland. "The Russian invasion of Ukraine and the mobilization declared by Russia have changed the security situation in Europe," Finland’s Ministry of Foreign Affairs said in a statement on Thursday.
