MOSCOW, April 13 (RAPSI, Artem Ponomarev) – Russia’s Supreme Court on Wednesday declined to reduce sentence for three men from Dagestan, Rustam Alimirzayev, Tazhutdin Gadzhiyev and Sirazhul Ramazanov, convicted of terrorism, RAPSI reports from the courtroom.

In July 2015, The North Caucasus District Military Court sentenced Alimirzayev, Gadzhiyev and Ramazanov to 15, 9 and 11 years in prison respectively.

Defense lawyers for the convicts claimed that the ruling was illegal and groundless and asked the court to overturn it. The defendants pleaded guilty only of accessory to illegal military groups. Alimirzayev, Gadzhiyev and Ramazanov said that they had supplied food and clothing to terrorists.

According to investigators, Alimirzayev, Gadzhiyev and Ramazanov were members of a terrorist sabotage group led by Gasan Abdullayev that operated in the southern Dagestan.

In September 2013, one of the armed group’s members, Azim Mukailov, rammed through the fence  and drove in a car rigged with explosives into the yard of a district police station in Dagestani village of Khuchni. An immigration official and one policeman died; 17 people including 14 police officers were injured in the attack.
