The injured employee was taken by helicopter to the town of Longyearbyen with injuries that are not life-threatening. As the cruise line explained via a statement on their Facebook page, "A polar bear guard - an expert employed by the cruise line - was attacked on land by a polar bear".
Meanwhile fellow Twitter user Gareth Stringer commented: "Polar bear shot for being a Polar Bear".
Arctic tourism, now in high season, has been on the rise in recent years.
A polar bear has been shot dead after injuring a guard working for cruise ship tourists visiting an Arctic archipelago in Norway.
"The incident occurred when the four-person polar bear guard team, who are always on board for these expedition cruises as required by law, prepared for a shore leave", the company said.
"He was flown out, was responsive, and is now undergoing medical treatment", spokeswoman Negar Etminan said of their employee, adding that the victim was not in a life-threatening condition.
Polar bears have become poster animals for climate change, with scientists identifying human-driven global warming as the biggest threat to the bears' continued existence.
"Let's get too close to a polar bear in its natural environment and then kill it if it gets too close". "On the contrary", the statement explains, "polar bears are only observed from aboard ships, from a safe distance".
"And it should be remembered that our crew members are extremely competent in polar matters and bring years of experience to bear in this region".
