In an indictment released on Wednesday, Prosecutor Mehmet Yesilkaya said he sought life term for MP Enis Berberoglu of the opposition Republican People's Party, accusing him of "aiding an armed terrorist organization knowingly and intentionally without being a member."
Yesilkaya further accused the lawmaker of purportedly revealing "confidential information and documents of the state... and undertaking political or military espionage."
Back in May 2015, Cumhuriyet daily posted on its website footage showing Turkish security forces in early 2014 intercepting a convoy of trucks carrying arms for the militants in Syria.

Ankara denied the allegation and claimed that the trucks had been carrying humanitarian aid to Syria. However, Berberoglu defended the video, saying it was genuine.
Two prominent Cumhuriyet journalists were among other defendants in the case. Can Dundar and Erdem Gul were sentenced last year to at least five years in jail for revealing what was said to be state secrets.
The men were acquitted of espionage charges, which could have led to life sentences.
Turkey stands accused of supporting militant groups fighting to topple the Damascus government since March 2011.




American journalist Serena Shim didn't last long after reporting on what was crossing into Syria across the Turkish border.
Her assassination came off quite promptly.
