Austria's chancellor says he remains in favor of ending EU membership talks with Turkey, despite opposition from senior EU leaders, and is looking for support for his views within the 28-nation union.

Christian Kern's initial call to stop the negotiations earlier this month was rejected by EU Commission chief Jean-Claude Juncker as well as German and other EU government officials.

While critical of what they view as Turkey's eroding human rights, they fear for the future of a deal obliging Ankara to take back migrants arriving on Greek islands in exchange for funding to help care for refugees and visa-free travel in the EU for Turks.

Kern said Wednesday that the EU "cannot accept someone who does not honor democratic standards."

Turkey has harshly criticized the Austrian leader's views.
