Their investigation concluded that Turkish National Intelligence Organization (MIT) trucks had delivered containers with artillery shells, machine gun rounds and mortar shells to Syrian rebels.
Earlier in the day, the first hearing in the case was held at the 14th Criminal Court in Istanbul, at which requests by MIT and Turkish President Recep Tayyip Erdogan to be considered as plaintiffs were accepted, the Hurriyet Daily News newspaper reported.
Dundar and Gul were freed by the Constitutional Court one month before the start of their trial, to Erdogan’s consternation who said he refused to "accept, respect and follow" the ruling.
Dundar, the daily’s editor-in-chief, and Gul, its Ankara bureau chief, face a maximum life sentence for revealing state secrets. Both deny their guilt and claim the state violated their rights.
