Police in Turkey have detained 150 soldiers over alleged links to the U.S based preacher, Fethullah Gulen, who Ankara says orchestrated an attempted coup in 2016.

State-run Anadolu news agency today said those detained were among 300 military personnel, including 211 serving officers, facing arrest in an investigation by Istanbul prosecutors.

It said that police also detained more than 80 serving air force staff yesterday. Turkey declared a state of emergency and launched a massive crackdown after the coup, resulting in about 50,000 arrests.

More than 110,000 people were sacked from state jobs, including in the military. Gulen has denied involvement in the failed coup, in which 250 people were killed.
