With Erdogan seeking to rally national cross-party support for his rule 10 days after defeating the attempted putsch, he hosted two top opposition leaders for an unprecedented meeting at his presidential palace.
Over 13,000 people have been detained so far in a vast sweep in the wake of the July 15 military coup bid, which the authorities blame on the reclusive US-based Islamic cleric Fethullah Gulen.
The crackdown has raised tensions with the European Union, further hampering Ankara's stalled membership bid, while a potential diplomatic crisis with Washington is looming if the United States refuses to extradite Gulen to Turkey, a fellow NATO member.
Among those targeted were prominent journalist Nazli Ilicak who was fired from the pro-government Sabah daily in 2013 for criticising ministers caught up in a corruption scandal, it added.

The government says the stringent measures are needed to clear out the influence of Gulen from Turkey's institutions, claiming he has created a "parallel state" inside Turkey.
Gulen, 75, who lives in a compound in rural Pennsylvania and whose foundation runs a global network of schools, charities and media interests, has strongly denied the accusations.
