Turkish police have arrested more than 1,000 people in an operation across Turkey against a movement blamed for last summer’s failed coup.
Raids were continuing as authorities targeted a secret structure within Turkey’s police force.
Turkey says a movement loyal to U.S.-based Cleric Fethullah Gulen Organised the July 2016 plot to bring down President Recep Tayyip Erdogan.
Earlier this month the President has won a referendum on boosting his powers.
As a result of the narrow victory Mr Erdogan can become head of the executive, beefing up the largely ceremonial role of Turkey’s President.
