Turkish President Tayyip Erdogan signalled a fresh campaign against supporters of U.S.-based Muslim cleric Fethullah Gulen on Friday, vowing to pursue them "in their lairs". The pledge came a year after the emergence of corruption investigations targeting Erdogan's inner circle which he said was a plot to topple him orchestrated by a "parallel structure" of supporters of Gulen. The cleric, a former ally of Erdogan, denies the charge, Reuters reported. "We have gone into their lairs and we will go into them again. Whoever is beside them and behind them, we will bring down this network and bring it to account," Erdogan told a business forum in Ankara. -- SPA 19:27 LOCAL TIME 16:27 GMT تغريد
