A sign and barbed wire prevent entry to a road leading to a Turkish Cypriot-controlled area of Cyprus along the United Nations (U.N.) buffer zone in the district of Nicosia March 14, 2014. This year marks 40 years since the Cyprus National Guard staged a coup in Cyprus and the subsequent Turkish military intervention, which escalated a civil war between the Greek and Turkish Cypriot communities on the island. After the ceasefire, a heavily restricted U.N.-controlled buffer zone between the north and south of the island was put into operation. It stretches 180 km (112 miles) across the whole island measuring 7.4 km (4.6 miles) at its widest and 3.3 m (11 feet) at its narrowest point. It is restricted to the general public and no Greek or Turkish Cypriots are allowed inside. Picture taken March 14, 2014. REUTERS/Neil Hall (CYPRUS - Tags: POLITICS SOCIETY ANNIVERSARY)
