NICOSIA, Cyprus (AP) — U.N. Security Council member states must take part in a future summit aiming to remove a key stumbling block to a deal reunifying ethnically divided Cyprus, the island's government spokesman said Monday. Greek Cypriots reject a demand by the minority Turkish Cypriots to keep Turkish military intervention rights and troops in place after reunification, saying the European Union — of which Cyprus is a member — needs no third country security guarantees.
