A court in northwest Russia jailed on Friday...

Thirty people required hospitalization after an explosion caused the high-speed Nevsky Express train to derail.

The Novgorod court acquitted Salambek Dzakhkiyev and Maksharip Khidriyev, both residents of the Russian North Caucasus republic of Ingushetia, on terrorism charges, but found both guilty of the illicit trafficking of explosives. They were sentenced to ten and four years behind bars, respectively.

Both men pleaded not guilty. Lawyers for Dzakhkiyev and Khidriyev said they would appeal the verdict at the Supreme Court.

Prosecutors have said that Doku Umarov, a notorious Chechen warlord, was behind the attack. A former Russian soldier, Pavel Kosolapov, is suspected of making and planting the explosives.

In late November 2009, several cars of another Nevsky Express train from Moscow to St. Petersburg derailed after a bomb exploded on the tracks, killing 27 and injuring more than 90.
