Russia's security agency says a Lithuanian national has been sentenced to 13 years in prison for spying on Moscow.
The Federal Security Service (FSB), the main KGB successor agency, said on April 13 that Yevgeny Mataitis, who also has Russian citizenship, was arrested in the Russian exclave of Kaliningrad last year for allegedly sharing military intelligence with Lithuania.
"Carrying out tasks for the Lithuanian military intelligence, Mataitis collected and transmitted military information abroad, including state secrets, over the course of six years," the FSB said in a statement carried by Russian news agencies.
It said Mataitis had "completely admitted" his guilt.
Contacted by AFP, the FSB confirmed the statement but provided no further detail on Mataitis's sentence.
Russia's relations with the West have hit a post-Cold War nadir over the conflict in Ukraine, leading to a spike in spying claims.
