MOSCOW, February 7 (RAPSI) – Prosecutor has demanded to sentence three men, who stand charged with planning a terror attack in Moscow in 2015, to prison terms varying from 5 to 15 years, the Moscow District Military Court's spokesperson Irina Zhirnova told RAPSI on Tuesday.

The court was asked to sentence Mokhmad Mezhidov and Aslan Baysultanov to 15 years each and Elman Ashayev to 5 years in jail.

In 2015, the Federal Security Service (FSB) arrested a group of alleged terrorists who planned to organize an explosion at Moscow public transport. Investigators believe that terrorists attempted to intimidate Russian authorities to stop military operation against the Islamic State forces in Syria.  The Islamic State group, also called ISIS, is banned in Russia as a terrorist organization.

FSB chief Alexander Bortnikov announced earlier that the alleged mastermind behind the planned attack has come to Russia from Syria.
