Turkish authorities issued detention warrants for 115 people across 15 provinces over alleged links to last year's failed coup attempt, the Daily Mail said Friday, citing official Turkish reports.

The operations were aimed at breaking up the "financial structuring" of the network of US-based Fethullah Gulen.

Ankara blames Gulen for orchestrating the July 15 coup attempt last year and has repeatedly demanded the United States extradite him, so far in vain. Gulen denies involvement.
