ANKARA - Turkey on Tuesday summoned a top diplomat from the German embassy after Germany's spy chief said at the weekend he was not convinced a U.S.-based Muslim cleric was behind a failed coup attempt in Turkey last July. In a statement, Turkey's foreign ministry said the comments from BND head Bruno Kahl published in news magazine Der Spiegel on Saturday revealed a 'tolerant and protectionist attitude' towards what Ankara calls the 'Gulenist Terrorist Organisation.' The foreign ministry said it had summoned Berlin's charge d'affaires, a top diplomat who usually stands in when the ambassador is away.
