NICOSIA, Cyprus (AP) — The rival leaders of ethnically split Cyprus have asked the United Nations to prepare for a follow-up summit in early March that will aim to clinch a breakthrough on the difficult issue of how security will be handled after the island is reunified, a U.N. envoy said Wednesday. Espen Barth Eide said that Greek Cypriot President Nicos Anastasiades and the leader of the breakaway Turkish Cypriots, Mustafa Akinci, will in the meantime meet weekly to narrow differences on other outstanding issues. Fearing Turkey's might, 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.
