Twin polar cubs got their first look at the world today as they explored their enclosure at a zoo in Germany. The cubs emerged from their den with their mother Giovanna 14 weeks after they were born at Tierpark Hellabrunn in Munich. They were soon squabbling and rolling about in the mud, much to the delight of photographers.
