Turkish Airlines says it has fired 211 employees over their links to the Islamic transnational Gülen movement after the recent failed coup.

The state-run company sacked the workers, including management and cabin crew, as part of a purge of state institutions.

Dismissals occurred late on Sunday after it was decided the employees were linked to a religious movement President Tayyip Erdogan has said attempted to overthrow the government.

An official at Turkish Airlines, Europe's fourth-biggest carrier, declined to comment.

Other reports said the dismissals were due to "inefficiency."

Thelira.com, a financial-news website, said about 250 cabin crew were dismissed, along with 100 management and administrative staff.

Aviation news site Airporthaber.com said among those let go was a deputy chief executive responsible for the airline's financial affairs.

Authorities have sacked, suspended or detained some 60,000 people, mainly public-sector employees, after a failed coup by a small faction in the military. They are accused of sympathizing or belonging to a religious group led by Fethullah Gulen, an Islamic preacher in self-imposed exile in the United States.

Separately, landline operator Turk Telekom, which is 30 per cent state-owned, sacked 198 people on Friday in "cooperation with the security forces" and said some managers had been summoned by prosecutors for testimony in connection with the coup investigation, according to e-mailed statements.
