Russia has found another person guilty of espionage by providing confidential information to Ukrainian officials.
A regional court in Russia's western Bryansk region, which borders Ukraine, said on October 8 that Viktor Shur was found guilty of spying for Ukraine and sentenced to 12 years in prison.
Investigators said Shur had collected classified data related to Russia's security and handed that information to Ukraine's intelligence service.
Shur, who was arrested in December upon returning from Ukraine, reportedly pleaded guilty.
The trial was held behind closed doors.
The case against Shur is the latest in a series of treason cases in Russia amid the ongoing crisis in Ukraine's east.
More than 7,900 people have been killed in the military conflict between Ukrainian armed forces and pro-Russia separatists in parts of Ukraine's eastern Luhansk and Donetsk regions since April 2014.
