Turkish businessman and activist Osman Kavala turns 64 in İstanbul’s notorious Silivri Prison where he has been held in pre-trial detention since November 2017 on terror and coup charges.

Detained upon his arrival to İstanbul’s Atatürk airport late on Oct 18, Kavala is accused of “attempting to abolish the constitutional order” and “attempting to remove the government of the Turkish Republic,” according to media.

Media also said Kavala has been under investigation in the same probe that led to the jailing of US consulate employee Metin Topuz over alleged ties to Turkey’s Gulen group on Oct 4, 2017.

Turkish government accuses the group of masterminding the July 15, 2016 coup attempt while the latter denies involvement.
