ISTANBUL: Turkish police on Wednesday detained 20 people over their alleged links to a movement led by US-based Muslim cleric Fethullah Gulen, the state-run Anadolu Agency said.
It said the arrests were made in an operation carried out in the southern provinces of Osmaniye, Adana, Mersin and Isparta, and that teachers and businessmen were among those detained.

President Tayyip Erdogan accuses Gulen of setting up a "parallel state" and conspiring to unseat the government with a network of supporters in the judiciary, police and media.
Gulen, whose adherents run some schools and are active in the media industry, denies the charges.
The two men were allies until police and prosecutors seen as sympathetic to Gulen opened a corruption inquiry into Erdogan's inner circle in 2013.
