Turkish police today arrested 158 military officers on suspicion of links to the organization of the late preacher Fetullah Gulen, who is accused of masterminding a coup attempt in 2016, the Constantinople prosecutor’s office said.

According to the state-run Anadolu news agency, these arrests, which add to some 50 others made in late May, were made in 43 of the country’s 81 provinces, including those in Constantinople and Smir.

Another 18 military personnel are still wanted, the prosecutor’s office said, adding that these arrests mainly involve the ground army.

Fetullah Gulen, who died in late October in the U.S., where he lived for more than 25 years, was a close ally of Turkish President Rep. Tayyip Erdogan before becoming his sworn enemy.

Ankara accuses Gulen’s followers of infiltrating Turkish institutions, including the judiciary, armed forces, police and education, to create a “parallel state.”

Nearly 26,000 people accused of involvement in the Gülenist movement, which Ankara describes as “terrorist”, have been arrested since the failed coup attempt in 2016. Among them, more than 9,000 have been jailed, according to the Turkish judiciary.

After the death of the preacher, who has always denied any connection to that failed coup, President Erdogan vowed to pursue his followers to “the farthest corners of the world.”
