İstanbul-based Işık University fired another assistant professor on Tuesday after he refused to remove his support from a petition signed by fellow academics calling for the resolution of the Kurdish issue in Turkey.

Academic Sinan Birdal tweeted that the university management terminated his contract on Tuesday.

With the dismissal of Birdal, total number of those who have been purged from their positions since July 15, 2016, has reached 7,318.

Most of the academics who signed the petition named ‘Academics for Peace’ were either purged from positions or faced charges.

As the Turkish government continues a purge to cleanse Turkish universities of critics, 4,811 academics have been dismissed from 112 universities across the country through decrees issued during a state of emergency declared after a failed coup last summer, a report by the main opposition Republican People’s Party (CHP) had said on Monday.

According to a report by CHP deputy chairs Selin Sayek Böke and Zeynep Altıok, 15 universities out of 191 in Turkey were closed by government decrees issued during the state of emergency.

The report, titled “Dismissed academics, deserted universities” and presented to CHP Chairman Kemal Kılıçdaroğlu before its official release, said the ruling Justice and Development Party (AKP) imposed pressure on dissenting academics and thought that runs contrary to its ideology.
