A view of the departure lounge is seen from a former passport office in the abandoned Nicosia International Airport in the Nicosia District of Cyprus March 10, 2014. The airport which was subject to heavy fighting between Greek Cypriot and Turkish troops during the 1974 conflict has not been used since the ceasefire. 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 United Nations (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 10, 2014. REUTERS/Neil Hall (CYPRUS - Tags: POLITICS SOCIETY ANNIVERSARY TRANSPORT)
