Incredible images show a huge iceberg drifting dangerously close to the shore in Greenland this week. The towering structure has been edging closer to a harbour in Innaarsuit, where local authorities have issued warnings to the public. It is now near the Royal Greenland fish factory and the local food store, where people are being advised to take care when visiting.
