Estonian security official Eston Kohver has been sentenced to 15 years in prison for espionage and other charges by a court in Russia.

Despite the convicted pleading not guilty, Russia's domestic security service, the FSB, said he was on a "spying operation" on Russian territory.

Kohver was detained at the Russian border on last September in a case that provoked a diplomatic row.

Estonia and the EU insist the officer was abducted on Estonian soil.

After his arrest for spying near the Luhamaa border checkpoint on 5 September, the security official was charged with other crimes including smuggling arms and illegally crossing the Russian state border, according to Interfax news agency.

As well as the prison sentence, the court in the western Pskov region ordered him to pay a fine of 100,000 roubles (£970; €1,800).
