Talks aimed at re-unifying Cyprus collapsed On Friday as both sides reported deadlock.
One of the key issues that remain is what happens to the over 35,000 Turkish troops that remain in Turkish Cypriot region.
The Greek and Turkish Cypriot communities have been separated by a UN buffer zone since the conflict in 1974.
"Despite the very strong commitment and engagement of all the delegations and the different parties... the Conference on Cyprus was closed without an agreement being reached," the UN Secretary General, Antonio Guterres told reporters.
The UN Secretary General's Special Adivisor on Cyprus, Espen Barth Eide, tweeted, "Close but not close enough: a somber mood as delegations leave #CransMontana, after 10 days, without agreement".
The current round of talks took place in a Swiss resort.
