Ankara: Turkey's Ministry of Foreign Affairs summoned German charge d'affaires late Tuesday over German Federal Intelligence Service (BND) chief's remarks on Gulen, who Ankara believed was behind last year's failed coup.

The statement released by the foreign minister said that Turkey protested BND chief Bruno Kahl's remarks that he was not "convinced" about Fetullah Gulen's role in the botched July 15 coup attempt, Xinhua reported.
