[European Union foreign policy chief Mogherini talks to the media as she arrives at the EU Summit in Brussels]The European Union and Turkey share a "common interest" in resolving the dispute over the divided island of Cyprus in the coming months, Federica Mogherini, who oversees foreign affairs for the European Commission, said on Friday. Turkish and Greek Cypriots are negotiating now to reunify the island, split along ethnic lines since a 1974 invasion by Turkey in response to a short-lived Greek Cypriot coup. The division has been a major hurdle in advancing Turkey's bid to join the EU.
