Opposition Republican People's Party (CHP) Deputy Enis Berberoğlu was sentenced to 5 years and 10 months in jail on Tuesday for leaking secret documents in the controversial "MIT trucks" case.

Berberoğlu was accused of supplying confidential information regarding the country's intelligence service to two journalists, Can Dündar and Erdem Gül, who have both been charged with willfully aiding a terrorist group without being a member.

The CHP deputy was found guilty of disclosing secret state documents by the 2nd Penal Department of the Istanbul Regional Court of Justice.

Istanbul's 14th Heavy Penal Court initially sentenced Berberoğlu to 25 years in prison, but his case was later transferred to the Istanbul Regional Court of Justice.

In January 2014, trucks belonging to the National Intelligence Organization (MIT) carrying aid to northern Syria, where Turkmens had been exposed to heavy airstrikes and attacks from the Bashar Assad regime, were intercepted by security forces on orders of former Adana Public Prosecutor Özcan Şişman and Brig. Gen. Hamza Celepoğlu.

The supplies in the trucks were seized and MIT agents were handcuffed before being detained. The case stunned the nation, as it was the first time that the military explicitly intervened with the intelligence agency. The operation was conducted hurriedly and the governor of the province was informed about the incident in its latest phase.

It was later revealed that the raid was a plot by the Gülenist Terror Group (FETÖ) to embarrass and discredit the government via its followers who had infiltrated the military and judiciary.
