Negotiations to end the decades-old division of Cyprus broke down on Tuesday, with the two sides still far apart and no date set for a new round of talks.

It was the second round of meetings this month between Nicos Anastasiades, the Greek Cypriot leader, and his Turkish Cypriot counterpart, Mustafa Akinci.

The talks in Switzerland were supposed to produce a map of the internal boundaries of a future federation on Cyprus and pave the way for broader talks early next year.

But the two-day session broke up without progress, and each side blamed the other.

The internationally recognized Greek Cypriot government held Turkey responsible and said it was “not a good night for our country.”
