A Russian court has sentenced amateur ballerina Ksenia Karelina to 12 years in jail for treason for donating $51 (£39) to a charity supporting Ukraine, Ednews informs via BBC.

Karelina, who has American and Russian citizenship, pleaded guilty last week after a trial held behind closed doors.

She had been living in Los Angeles and became a US citizen in 2021. She was arrested during a family visit last January in Yekaterinburg, about 1,600km (1,000 miles) east of Moscow.

Prosecutors had sought a 15-year jail term. The court in Yekaterinburg found her guilty of high treason and sentenced her to imprisonment in a general regime penal colony.

Karelina had been accused by Russia's FSB security service of raising money for a Ukrainian organisation providing arms to the Ukrainian military.

Russian human rights activists said while living in the US she had made a single transfer of $51.80 on the first day of Russia's full-scale invasion of Ukraine on 22 February 2022. The FSB is thought to have discovered the transaction on her phone.

Her lawyer, Mikhail Mushailov, said Karelina had only admitted transferring the money and believed the funds would help victims on both sides. He told Russian media she would appeal against the sentence.

The charity, Razom for Ukraine, said earlier this year it was "appalled" to hear of the amateur ballerina's arrest and denied raising money for weapons or ammunition. It said it was a US-founded charity focused on humanitarian aid and disaster relief.

Karelina went on trial in June in the same court as Evan Gershkovich, the Wall Street Journal reporter who was jailed for espionage but freed earlier this month as part of a major prisoner swap with the US and other Western countries.

The cases in Yekaterinburg were heard by the same judge, Andrei Mineev.
