Russian court has sentenced American citizen Gene Spector to 15 years in prison on charges of espionage, according to state news agencies. He will serve his sentence in a strict regime penal colony and has been fined 14 million rubles (approximately 134,000 euros). The trial was held behind closed doors, with no further details disclosed about the charges. Spector, who had already received a 3.5-year sentence for corruption, appeared to have pleaded guilty and reached a cooperation agreement with authorities. Speculation surrounds potential future prisoner exchanges between the West and Russia.
