The head of a Turkish parliamentary committee says, there is no doubt that US-based Muslim cleric Fethullah Gulen was behind last year's failed military coup.<br/><br/>Resat Petek made the statement today while presenting the report of a committee charged with investigating the attempt. Gulen, a former ally-turned-foe of President Recep Tayyip Erdogan, has denied he was involved.<br/><br/>Petek told reporters the report reveals that Gulen's movement was behind the July 15 event with clarity and certainty. Turkey has called Gulen's movement a terror organization and is seeking his extradition. The government has cracked down on his followers, arresting more than 47,000 people and dismissing over 10,000 others from government jobs.
