This is the moment polar bears invaded a remote Arctic region of Russia - only to be chased away by a pack of dogs. <br /><br />Video filmed last week (February 5) shows at least two polar bears walking in a residential area by people's houses in the night in the Novaya Zemlya archipelago, located in the Arctic Ocean. <br /><br />Valentina, the filmer and a resident of Novaya Zemlya, says that she was alerted to the predators walking by her window thanks to dogs barking. <br /><br />Video filmed from Valentina's first-floor apartment window shows what she believes to be a polar cub and its mother being barked at by a pack of dogs that surround them. Further video shows a polar bear running away from the chasing pack of dogs.<br /><br />Such situations are becoming more frequent in the area, as Valentina told Newsflare: "Dogs here are considered as our protectors and are highly valued. Once they start barking all together and really loudly, we know that bears are somewhere close."<br /><br />UK media reported this week that environmental authorities have deployed a team of specialists to the area to sedate and remove polar bears.<br /><br />"Of course people are scared," says Valentina. "We need to keep on turning around every time we walk to make sure nobody's following us."<br /><br />"Now the situation is not that bad - we have just several bears around. But two weeks ago it was worse, bears were invading every corner."<br /><br />Valentina even described a recent incident where she went for a walk with her child and on turning around, noticed a polar bear walk out from around the corner.<br /><br />Russia classes polar bears as an endangered species and shooting them is prohibited.
