It's been all over the news here in Norway the last couple of days, and it's tragic when these things happen.
But what is making this even more tragic is that it looks like they didn't secure their campsite good enough from polar bears (tripwire didn't go off, looks like they didn't hide the food good enough, not the best place for a campsite etc..).
This time of the year it is normally also not enough food for the polar bears on Svalbard, so they tend to get closer to humans due to that as well.
