The United Nations on today said the rival leaders on the divided Mediterranean island of Cyprus have made "real progress" in reunification talks, dpa reported. "They have made real progress," said UN Secretary General's Special Advisor for Cyprus, Alexander Downer speaking to reporters. "They have put more on paper now, of an agreed nature, than any time since 1974." The UN envoy said there was no fixed deadline to conclude the talks, which were progressing on a chapter-by-chapter basis. The eastern Mediterranean island has been divided into a Greek Cypriot south and Turkish Cypriot controlled north since a Turkish invasion in 1974, with peace talks only resuming in September last year after being broken off in 2004. The talks, in the buffer zone of Lefkosa in Cyprus, are being held under the aegis of the United Nations.
