Denmark on Monday summoned Turkey's charge d'affaires for talks after local media reported that Danish citizens of Turkish origin critical of President Recep Tayyip Erdogan claimed they had been tagged as traitors by Ankara.

Axar.az reports that the Danish Foreign Ministry said in a statement its foreign policy director "made it clear" that Denmark "saw with great concern" those reports about Danish citizens allegedly being registered by Turkish authorities accused of treason because of their political affiliation.

During the meeting, the charge d'affaires said Turkey denied registering Turks living in Denmark based on their political opposition to the government or even having such a registry.

Informing on Turks is only permitted in terrorism-related issues, the charge d'affaires said, according to the Danish ministry statement.

The Turkish charge d'affaires could not be reached for immediate comment.

On Saturday, Danish daily Berlingske reported that several Danish citizens of Turkish origin claimed to have been accused of treason by Ankara and placed on a list because of their political views.
