President Recep Tayyip Erdogan is vowing to go after businesses linked to a US-based Muslim cleric he accuses of having been behind Turkey's failed July 15 coup.

The Turkish government characterizes the movement of Fethullah Gulen, who lives in self-imposed exile in Pennsylvania, as a terrorist organization.

Speaking Thursday to the heads of chambers of commerce in Ankara, Erdogan said the government was "determined to totally cut off all business links of this organization, which has blood on its hands."

He added that "every cent" that goes to the Gulen movement "is a bullet placed in a barrel to be fired against this nation. In the same way that we do not pardon those who fire the bullet, we will not forgive those who financed the bullet."
