Jörg Brase, Istanbul bureau chief for ZDF public television, and Thomas Seibert, who writes for the newspaper Tagesspiegel, have had their applications for press cards rejected by the Turkish government.
Senior German foreign ministry official Andreas Michaelis called Turkey's ambassador to Germany to protest the decision and asked Ankara to reconsider, the ministry said.
“The decision is incomprehensible,” said ministry spokeswoman Maria Adebahr.
Relations between Berlin and Ankara plummeted after Turkish authorities arrested tens of thousands of people in a mass purge over the 2016 attempted coup against Turkish President Tayyip Erdogan. Some of those arrested were also German nationals.
A gradual rapprochement began in 2018 after German-Turkish journalist Deniz Yücel was freed following his arrest the year before.
Another journalist, Meşale Tolu, was allowed to return to Germany in August
Both still face terror-related charges in Turkey.
