The Turkish foreign ministry has strongly condemned what it describes as the “unjust decision” of a top European rights body to put it on a monitoring watch list.
Ankara says it has been left with no choice but to reconsider its relations with the organisation.
“Deciding to re-open the monitoring procedure of malicious circles at the PACE is a disgrace to this organ, which claims to be the cradle of democracy,” the ministry said in a statement.
Xenophobia and Islamophobia are “spreading with violence” across Europe, it added.
The Council of Europe’s Parliamentary Assemby (PACE) has put Turkey on a monitoring watch list.
There are concerns over what they say is the stifling of dissent and rights violations under President Recep Tayyip Erdogan.
