Turkey on Wednesday deepened a crackdown on suspected followers of a U.S.-based cleric it blames for a failed coup, dismissing nearly 1,700 military personnel and shutting 131 media outlets, moves that may spark more concern among its Western allies.

So far, tens of thousands of people — including police, judges and teachers — have been suspended or placed under investigation since the July 15-16 coup, which Turkey says was staged by a faction within the military loyal to the Muslim cleric Fethullah Gulen.

Gulen, who lives in self-imposed exile in Pennsylvania but whose movement has a wide following in Turkey where it runs a large network of schools, has denied any involvement in the failed putsch.
