Ankara on Monday said US-based Muslim preacher Fethullah Gulen, blamed for last year's failed coup, and dozens of others would lose Turkish citizenship if they did not return home within three months.
A total of 130 people will be affected by the move, an Interior Ministry announcement published in the Official Gazette said, adding that the three-month deadline started on Monday.
The Government says the abortive July coup aimed at toppling President Recep Tayyip Erdogan was engineered by an Islamic movement led by Gulen, who has denied the charges.
The list also includes two lawmakers from the pro-Kurdish Peoples' Democracy Party (HDP) Faysal Sariyildiz and Tugba Hezer.
