ANKARA/ISTANBUL—Turkey’s relations with the European Union appeared to take a turn for the worse on Tuesday, as Ankara voiced dissatisfaction with the result of last week’s EU summit and the bloc said the country’s bid for membership was evaporating.
Tensions between the EU and Ankara had eased in recent weeks as Turkey and EU member Greece agreed to hold exploratory talks to solve several longstanding disputes, including a standoff over maritime claims in the eastern Mediterranean.
