A Moscow court has found a Norwegian man guilty of espionage and sentenced him to 14 years in a high-security prison.

Retired Norwegian border inspector Frode Berg was arrested in Moscow in December 2017. He was accused of collecting information about Russian nuclear submarines for Norwegian intelligence.

He denies the charges and his lawyer has called him a victim of a setup.

Asked about a possible pardon for Berg, President Vladimir Putin said last week that he would wait for the verdict before weighing pleas for one.
