Talks between Turk and Greek Cypriot leaders began in Switzerland today. <br/><br/>Greek Cypriot leader Nicos Anastasiades and his Turkish Cypriot counterpart Mustafa Akinci are joined by EU foreign policy chief Federica Mogherini and foreign ministers from Greece, Turkey and Britain for the early stages of the talks dealing with security issues. <br/><br/>Cyprus has been divided since 1974, when Turkish troops invaded its northern third in response to an Athens-inspired coup seeking union with Greece. The last round of talks in January failed to make any headway.
