It's unclear where the clip was shot, but according to the video's title (in Russian) the trappers are Yakuts, native to Siberia. Although they lost their ill-gotten "prize," even they can be heard laughing to see the arctic fox make his getaway.
Sadly, most arctic foxes in such a dire situation never escape. Despite the horrors of fur trapping, this practice remains the largest threat to the species, and not only in Russia. It is still legal for licensed trappers in Norway, Greenland, Canada, and Alaska to catch foxes in that manner, leaving them unprotected in the majority of their native range.
