In July 2015, German prosecutors reportedly examined allegations that three men—two Turkish nationals and one German citizen—had been instructed by Turkey’s National Intelligence Organization (MIT) to spy on critics of President Recep Tayyip Erdoğan in Cologne, including Kurdish activists and members of the Alevi community. In 2016, members of the Bundestag’s Parliamentary Oversight Panel demanded answers after reports that Turkish-origin residents were being pressured by informants and intelligence officers operating in Germany.
The allegations intensified in March 2017, when German officials said MIT had provided information on more than 300 people and roughly 200 associations and schools allegedly linked to supporters of exiled cleric Fethullah Gülen. The reported list included politicians such as Michelle Müntefering. Lower Saxony Interior Minister Boris Pistorius called the activity “intolerable and unacceptable,” while federal Interior Minister Thomas de Maizière warned it could be intended to damage German-Turkish relations. German media also reported in October 2017 that immigration officials had passed information about Turkish asylum seekers to Ankara, potentially exposing their locations. The episode prompted parliamentary scrutiny and heightened concerns over foreign-government intimidation inside Germany.
