A key aide to the US-based Muslim cleric blamed by Turkey for a failed military coup has been captured by Turkish forces, a presidency official has said.
President Recep Tayyip Erdogan has blamed Fethullah Gulen for the unsuccessful bid to overthrow the government, which Gulen has denied.
Halis Hanci, described as Gulen's "right-hand man", reportedly entered Turkey two days before the coup attempt began, the official said.
It comes just hours after his nephew Muhammed Sait Gulen was detained in Erzurum in northeastern Turkey.
Nearly 1,700 military personnel have been sacked and 130 media outlets shut down as the crackdown continues following the failed coup.
The dispatch comes after President Erdogan called on US to hand over cleric Fethullah Gulen, who he blames for Turkey's failed coup.
Turkey has been warned of the consequences of imposing the death penalty as punishment to those involved in the failed coup attempt.
