Two former defense workers were sentenced in Russia to 17 and 13 years in prison for treason on Tuesday after being found guilty of passing military intelligence to Ukraine and planning to blow up railway lines, the Kursk Regional Court said in a statement.
The couple, who were formerly married, were arrested last month by the FSB security service in the Kursk region, near the border with Ukraine, and accused of handing over technical documents and models used in the manufacture of weapons systems for Russia's air force.
