MOSCOW, November 27 - RAPSI. The Moscow City Court will announce the sentence in the case of the planned terrorist attack on a high-speed train between St. Petersburg and Moscow on December 10, the court's press service told the Russian Legal Information Agency (RAPSI/rapsinews.com).

Arguments were presented in court on Monday, with the prosecutors seeking sentences of 16 to 19 years for the defendants.

The defense requested the full acquittal of one of the defendants, and the acquittal of the other three defendants of attempting to commit acts of terrorism, since they voluntarily chose not to go ahead with the plan.

The case has been considered by a three-judge panel.

Islam Khamzhuyev, Fail Nevlyutov, Mansur Umayev, and Mansur Edilbiyev have been accused of attempting to commit acts of terrorism, as well as illegally acquiring, transferring, selling, transporting, and possessing arms and explosive devices.

Khamzhuyev, Umayev, and Edelbiyev have also been charged with illegally manufacturing explosives. Nevlyutov has been charged with taking part in an illegally armed enterprise.

Khamzhuyev has also been accused of financing an illegally armed criminal enterprise.

On July 18, 2011, Federal Security Service (FSB) head Alexander Bortnikov reported to then-President Dmitry Medvedev that a major terrorist attack had been averted in the Moscow region, and four suspects had been detained. He said an explosive device, arms, and a map had been seized.

It later became known that they had planned to blow up a Sapsan train, a new high-speed train which runs between Moscow and St. Petersburg, and Moscow and Nizhny Novgorod.
