Tourists warned to keep away as thousands of walruses descend on remote village

A remote village on the north-west coast of Alaska has begun a reverse tourism campaign - residents want visitors to stay away.
Pacific walruses by the thousand have come ashore in early autumn near the Inupiat village of Point Lay in recent years, including about 6,000 last week, and people have dropped in, hoping to see a phenomenon brought on by climate change and disappearing summer ice in the Chukchi Sea.
