NICOSIA, Cyprus (AP) — An official says high-level talks to reunify ethnically divided Cyprus failed to reach a deal amid Turkey's insistence to keep its troops on the island and to maintain the right to militarily intervene.

The official said negotiators on Friday also failed to agree on how much territory would make up the Greek Cypriot and Turkish Cypriot zones in an envisioned federation. The official spoke on condition of anonymity because he's not authorized to disclose details of the sensitive meeting.

He also said Turkey also insisted that any peace accord must grant Turkish nationals the right to relocate and transfer money, services and goods to a reunified Cyprus.

Marathon negotiations have been held in the presence of U.N. Secretary-General Antonio Guterres at the Swiss resort of Crans-Montana.
