Turkish President Recep Tayyip Erdogan on Tuesday demanded international action against the US-exiled preacher Fethullah Gulen, whom he accuses of orchestrating an aborted coup d'etat against him.

"I would like to call on all our friends to take the necessary measures against the Fethullah Terrorist Organization in their own countries for the future of their own people and their well-being," he told the UN General Assembly, referring to Gulen's movement.
