Russian authorities say an officer of Russia's Black Sea fleet and his partner have been imprisoned on charges of spying for Ukraine.
Russia's North Caucasus Regional Military Court sentenced Major Dmitry Dolgopolov to 10 years in prison and Anna Sukhonosova to 9 years after convicting the couple of selling classified materials to Ukraine's Security Service (SBU).
Both the Federal Security Service (FSB) and the Russian military court described Sukhonosova as Dolgopolov's "common-law wife."
The two were arrested in September 2017 in Ukraine's Russian-occupied region of Crimea. Russia’s Black Sea fleet is based at the Crimean port of Sevastopol.
The FSB statement said Dolgopolov and Sukhonosova pleaded guilty to the charges.
"The named individuals collected and handed to Ukraine’s Security Service materials containing state secrets on operations of units of the Black Sea Fleet," an FSB statement said.
