Turkey has been operating an informer network via its embassy in Vienna that targets critics of President Tayyip Erdogan, according to an Austrian opposition lawmaker, Peter Pilz.

Pilz also said the controversial network promotes Erdoğan’s policies and receives payments from Ankara.

Reuters reported on Tuesday that Pilz had sent documents to the police detailing the activities of the ATIB, an umbrella organization headed by the religion attaché at Turkey’s embassy that oversees dozens of mosques in Austria.

ATIB and the Turkey’s foreign ministry rejected accusations.

Pilz said Turkish imams sent by Ankara to work for ATIB were providing information in particular about the Gülen movement, Reuters further said.

Earlier, German authorities launched investigation into Turkish imams affiliated with Turkish-Islamic Union for Religious Affairs (DİTİB) who were alleged to have been spying on Erdoğan’s critics.

A document dated Sept. 20, 2016 said that the Turkey’s religious directorate Diyanet asked Turkish missions and religious representatives abroad to profile Gülen movement expatriates living in their respective countries.
