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 dancer poses with a new installation of art by British graffiti artist Banksy painted on the front door of the Hustler Club in New York, October 24, 2013. Known for his anti-authoritarian black-and-white stenciled images, which have sold at auction for upwards of $2 million, the British street artist is treating New Yorkers to a daily dose of spray-painted art – while eluding the police and incurring the wrath of New York Mayor Michael Bloomberg.

Palestinians hit injured Israeli settlers, center, detained by Palestinian villagers in a building under construction near the West Bank village of Qusra, southeast of the city of Nablus, Tuesday, January 7, 2014. Palestinians held more than a dozen Israeli settlers for about two hours Tuesday in retaliation for the latest in a string of settler attacks on villages in the area, witnesses said. The military said the chain of events apparently began after Israeli authorities removed an illegally built structure in Esh Kodesh, a rogue Israeli settlement in the area. In recent years, militant settlers have often responded to any attempts by the Israeli military to remove parts of dozens of rogue settlements, or outposts, by attacking Palestinians and their property. The tactic, begun in 2008, is known as “price tag”. (Photo by Nasser Ishtayeh/AP Photo)
