There's been some talk in here about alleged spying in Norway, with some arrests made. Drones and the like. I don't think much is known about those cases yet, but one person arrested in Svalbard is Andrey Yakunin, son of Vladimir Yakunin who has pretty close ties to Putin (
Wiki link).

What the cases involving drones mean is hard to say, because with the sanctions it's illegal no matter how benign the filming is so it can be anything. In this specific instance it's also a bit more unclear about the legalities with Svalbard having some laws about discrimination based on nationality that may or may not be relevant here.
