The Turkish intelligence agencies have raised alarms over a reported death attempt plot against Ogun Samast, a Turkish nationalist jailed over charges of the assassination of Hrant Dink, the editor-in-chief of the Armenian-Turkish weekly Agos.

According to the Turkish newspaper Star, the Turkish National Intelligence Organization's (MIT) confidential letter on the reported plot has been sent to the Istanbul juvenile court, the prison administration, the Istanbul intelligence service, and the Istanbul provincial gendarmerie.

"It is planned to launch an armed attack on the vehicle that periodically transports Ogun Samast from jail to court," says the MIT statement.

The Turkish intelligence claims that the attack will be launched by the leftist Turkish Workers and Villagers Organization (TIKKO) whose armed rebels are reportedly planning to bomb the vehicle.

Samast, who is being kept in the Kojaeli prison, stands trial at the Istanbul juvenile court.
