A Lithuanian court has sentenced a former employee of the country's air traffic control service to three years and three months in prison after finding him guilty of spying for Belarus.

The Vilnius district court on Thursday ruled that 57-year-old Romualdas Lipskis had provided information on Lithuania's military and strategically important companies to the Belarusian intelligence service.

Lipskis, who was arrested in 2013, said he would appeal, because "I know I am not guilty."

Prosecutors told the court that that the Belarusian service shares information with Russian counterparts and that the information collected by Lipskis was likely intended for Moscow.

The Belarusian Embassy in Vilnius did not comment on the case.
