A bit more information on this:



That statement was sent out by the government to one of the opposition parties (The Lefts). It's an answer to what is called an "enquiry", an inherent part of the German governmental system. Opposition parties can enquire about different topics and the government is obliged to answer truthfully.



The "risky" part of that answer was classified, but it got leaked to one of the public broadcasters in Germany.



The important parts of that statement read as follows (translation by me):



"The numerous statements of solidarity and acts of support for the Muslim brotherhood, Hamas as well as the armed Islamistic opposition in Syria carried out by the AKP and Erdogan emphasise their ideological affinity towards the Muslim brotherhood."



"As a result of Ankara's islamised domestic and foreign policy, starting in 2011, Turkey developed into the central platform for action of Islamistic groups in the Near and Middle East."
