When it comes to hugging, polar bears really know their stuff - as these adorable photos prove.

Photographer and zoo worker Sussi Kober caught the touching moment between mother and son bear at Aalborg Zoo in Denmark.

In the series of pictures, one-year-old Augo looks almost as if he's being told off by his mum Malik before winning her over with a giant hug.

"Augo is a playful little bear and enjoys playing around and being mischievous," explained Sussi. "Sometimes it seems as if he is testing his mother, but he will always win her over with some affection."

Enjoy the heart-warming photos, above and below.
