Germany-based Turkish-Islamic Union for Religious Affairs (DİTİB) said some of its preachers acted as informants against the sympathizers of the Gülen movement, which the government accuses of attempting a military coup on July 15.

Denying any involvement from the beginning, the movement has been complaining that Turkish government is using every means to round up its followers whether be in Turkey or abroad.

DİTİB said in a report published in the “Rheinische Post” newspaper on Jan 12 that some of its preachers spied at Turkey’s request.

The Germany’s biggest largest Turkish Islamic group earlier denied allegations that Turkish Turkey’s Directorate of Religious Affairs (Diyanet) ordered DİTİB to report on the activities of the Gülen movement.

DİTİB said “some imams wrongly” informed on suspected Gülen followers in Germany.

“We deeply regret this mishap and have spoken to Diyanet about this,” DITIB Secretary-General Bekir Alboga told Rheinische Post, according to Deutsche Welle.

DİTİB should provide German authorities the names of the imams who collected information or acted on the orders of the Turkish government, Volker Beck, a lawmaker for the opposition Greens told Deutsche Welle.

A document dated Sept. 20, 2016 previously that Diyanet asked Turkish missions and religious representatives abroad to profile Gülen movement expatriates living in their respective foreign countries.
