An İstanbul court has issued an arrest warrant for former editor-in-chief of the Cumhuriyet daily and exiled journalist Can Dündar to compel his testimony in a trial concerning the now shut-down pro-Kurdish Özgür Gündem daily.

The İstanbul 22nd Penal Court issued the warrant on Thursday, with the prosecutor demanding his imprisonment for supporting terrorist organization publications.

The first hearing has been set for April 11, 2017.

Dündar published a sensational report on Turkey’s alleged illegal arms delivery to opposition groups in Syria. Following his story, President Recep Tayyip Erdoğan personally targeted him, calling him a traitor. Dündar has been living in Germany, which Erdoğan accuses of harboring terrorists.
