I have no idea about Russians being camped on our border, there have been rumors in the social media that there would be some troops heading our way but that's not confirmed by any trustworthy media, person or the government. And if there are few armored vehicles moving, that's nothing abnormal. The rumor might just be something the Russian trolls and people working for Russian favor are trying to spread in order to spread fear. But we here in Finland are used to every other month border trespassing from Russian behalf by air or see. One plane or a ship "lost" for a moment to the Finnish side or some excuse. They are just trying out our response time.
Have a great day!
You too, have a good one, lovely weather here in Poland today.
