General view of the monument to memory of soldiers who liberated the city of Knin – in Knin, Croatia on November 10, 2014. Across the former Yugoslavia stand giant monuments to a state that no longer exists, once visited and celebrated during public holidays such as Republic Day on November 29, marking the creation of socialist Yugoslavia. Many are now neglected or ignored, aging symbols of a joint state forged during World War Two but torn apart by nationalism half a century later. Republic Day is no longer marked in any of the seven independent states that emerged from its ashes. (Photo by Antonio Bronic/Reuters)

A camel yawns as a tourist checks images on her camera following a ride on a camel safari alongside the Pacific Ocean on Lighthouse Beach, north of Sydney, December 4, 2014. For 25 years camel rides on this beach have given visitors to Australia's holiday coast a rare experience available only in a handful of locations in the country. Australia's long history with the “ships of the desert” goes back to the 1800s when they were imported from Afghanistan and India for use as transportation across Australia's vast deserts before being released into the wild following their replacement by motorised transport.
