Two Turkish opposition journalists accused of espionage and trying to overthrow the government in a case that has caused global concern are due to go on trial next month.

Cumhuriyet newspaper's editor-in-chief Can Dundar and Ankara bureau chief Erdem Gul have been detained for more than two months over an article that alleged President Recep Tayyip Erdogan's government tried to send arms into Syria.

The report sparked a furore in Turkey, fuelling speculation about the government's role in the Syrian crisis and its alleged relations with the ISIL terrorists leading the fight against the Syrian army.
