Turkish authorities have issued detention warrants for a total of 192 military personnel over alleged links to the Gülen group, accused of orchestrating a failed coup two years ago, Reuters reported on Wednesday, citing authorities and media.

Among the military personnel sought by the Ankara prosecutors are one former brigadier general and 30 pilots, 99 members of the air force.

It said the detainees were suspected of being in contact with the network of the cleric, Fethullah Gülen, and of communicating with it via periodic pay phone calls, a method believed to be used by supporters of the group.

In a separate series of operations, authorities ordered the detention of 93 personnel from the army, navy and coast guard, the state-run Anadolu news agency reported.

Authorities have regularly conducted such sweeps against alleged supporters of Gülen since the coup attempt in July 2016, in which 249 people were killed. Gülen, who has lived in self-imposed exile in Pennsylvania since 1999, denies involvement.

On Tuesday Turkish authorities ordered the detention of 132 people in nationwide operations.

In total, Turkey has detained some 160,000 people and dismissed nearly the same number of state employees since the coup attempt, the United Nations said in March. Of those, more than 50,000 have been formally charged and are being kept in jail during trial.f
