Germany’s foreign minister criticized Turkey for refusing to issue credentials to foreign reporters, saying in an interview published Sunday that such actions were “not compatible with our understanding of press freedom,” AP reported.

The comment by Foreign Minister Heiko Maas followed several foreign correspondents recently having applications to renew their accreditation to work in Turkey rejected.

“It can’t be ruled out that the Turkish government will take further measures against representatives of German media as well as civil society organizations,” the ministry said.

Germany is cautioning its citizens to be careful about their social media activity when visiting Turkey.

The dpa news agency reported Wednesday that Germany’s official travel advice has been revised to warn about the risk of criticizing Turkey’s government on social media.

The German foreign ministry says that “in individual cases it’s enough to share or ‘like’ another person’s comment” for people to get into trouble.
