Turkey has protested to foreign missions over the presence of consuls from EU states at the espionage trial of Cumhuriyet daily's Can Dündar and Erdem Gül, and their comments online, a diplomatic source said Monday.

"We have conveyed our discomfort to the concerned countries' representatives over the comments shared on social media which may constitute interference in the independent judicial process and which do not comply with impartiality," the source said.

The trial of two top journalists from the Cumhuriyet daily last week was attended by top diplomats including the British consul to Istanbul, who published pictures from the court on Twitter.

Dündar, who serves as editor-in-chief of Cumhuriyet, and Gül, who serves as Cumhuriyet's Ankara representative, were arrested last year after publishing a controversial report regarding the National Intelligence Organization (MİT).Dündar and Gül were responsible for publishing footage regarding an unlawful raid that targeted trucks belonging to the National Intelligence Agency (MİT) in early January 2014.
