Two men cross Ledra Street, next to the UN buffer zone in divided Nicosia, Cyprus, yesterday. Cyprus President Dimitris Christofias cut short his visit to London because of problems that forced the brief closure of the crossing hours after it opened for the first time in decades. Greek-Cypriot police shut down the crossing late on Thursday for two hours after Turkish-Cypriot police were seen inside the buffer zone that separates the capital.
