A Turkish prosecutor has issued detention warrants for 90 soldiers, including high ranking military officers, as part of an ongoing investigation into the Gülen movement, which is accused by Turkish government of orchestrating a failed coup in Turkey last summer.

According to a Friday report by CNNTürk, 50 of the wanted soldiers have so far been been detained in operations carried out simultaneously in 15 provinces across Turkey. The operations are continuing for the soldiers still at large.

The coup attempt on July 15 killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AKP) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement.

The movement denies any involvement.

The Foreign Affairs Committee of the UK Parliament concluded last week that Gülen and the movement he inspired as a whole were not behind a failed coup attempt in Turkey on July 15.

The committee concluded that “given the brutality of the events of 15 July, the severity of the charges made against the Gülenists, and the scale of the purges of perceived Gülenists that has been justified on this basis, there is a relative lack of hard, publicly–available evidence to prove that the Gülenists as an organisation were responsible for the coup attempt in Turkey. While there is evidence to indicate that some individual Gülenists were involved, it is mostly anecdotal or circumstantial, sometimes premised on information from confessions or informants, and is—so far—inconclusive in relation to the organisation as a whole or its leadership.”

The UK Parliament statement came a week after Germany rejected Erdoğan and the Turkish government’s accusations against the Gülen movement about July 15.

The head of Germany’s Federal Intelligence Service (BND), Bruno Kahl, said Turkey could not convince them that US-based Turkish-Islamic scholar Gülen was behind a failed coup attempt on July 15.
