COPENHAGEN, Denmark — The Baltic News Service says Estonia and Russia have exchanged two men convicted of espionage at a border crossing between the two countries.

The region’s main news agency cited Estonia’s Internal Security Service as saying that Raivo Susi, an Estonian found guilty of espionage and sentenced to 12 years in a high security prison in Russia, had been exchanged Saturday for Artern Zintsenko, who had been given five years by Estonia for spying for Russia in May.

Estonia’s security agency said “Estonia extradited to Russia a spy who committed a crime here and the Estonian entrepreneur was able to return to his loved ones after a long retention in Russia.”

There was no immediate confirmation from Moscow.
