Members of the European Parliament have passed a report calling for Turkey's EU accession talks to be suspended, amid concerns over constitutional changes made by Turkish President Recep Tayyip Erdogan.
However, amendments to the report calling for talks to end permanently were rejected.
The report, whose recommendations are not binding, was compiled by the European Parliament's foreign affairs committee.
The Turkish president narrowly won backing for the changes in a controversial referendum in April.
Turkey said it does not accept the call by the European Parliament, with its EU Affairs Minister Omer Celik saying it was a political decision which Ankara regarded as invalid.
A Turkish foreign ministry spokesman said the decision was based on false claims and allegations, and undermined the parliament's reputation.
Meanwhile EU commissioner Johannes Hahn said he had raised with the Turkish government the need to respect the rule of law and that people have the right to a fair trial.
Mr Hahn said he also brought up the issue of human rights activists who were detained yesterday, but had not received a sufficient answer.
He was speaking to reporters at the end of a visit to Turkey during which he met Prime Minister Binali Yildirim and other government ministers.
