Turkey's state-run news agency says police have launched simultaneous raids in a dozen cities, detaining at least 23 people — including journalists, television producers and police — known to be close to a movement led by a U.S.-based a moderate Islamic cleric

The government accuses the cleric Fethullah Gulen's movement, a former ally, of orchestrating an alleged plot to try and bring down the government. It says the group's followers were behind corruption allegations that last year forced four Cabinet ministers to resign.

The Anadolu Agency says a court has issued a warrant to arrest 32 people connected to the group and 23 of them were detained in raids early Sunday.
