A Russian court on Thursday jailed US-Russian citizen Ksenia Karelina for 12 years after she was found guilty of "high treason" for giving about $50 to a pro-Ukraine charity in a case slammed as "vindictive cruelty" by the US presidency.
The 32-year-old ballet dancer and spa worker from Los Angeles was detained in the Urals city of Yekaterinburg in January while visiting family.
"The court found Ksenia Karelina guilty of high treason and sentenced her to 12 years' imprisonment in a general regime colony," the Sverdlovsk Regional Court in Yekaterinburg said.
Karelina stood in a glass defendant's cage wearing a white top and jeans as the verdict was read out, a video posted by the court showed.
She donated $51.80 to New York-based charity "Razom for Ukraine" shortly after Russia launched its full-scale military offensive in February 2022, US media outlets reported, citing her family and employer.
Russia's FSB security service accused her of collecting money that was "used to purchase tactical medical supplies, equipment, weapons and ammunition for the Ukrainian armed forces."
She pleaded guilty to the charges at a hearing last week, state media said.
The White House denounced the court verdict as "nothing less than just vindictive cruelty".
"We're talking about 50 bucks to try to alleviate the suffering of the people of Ukraine and to call that treason is just absolutely ludicrous," National Security Council spokesman John Kirby told reporters.
Washington has accused Moscow of arresting its citizens on baseless charges to use them as bargaining chips to secure the release of Russians convicted abroad.
The sentence was ordered just over two weeks after Russia freed US reporter Evan Gershkovich, former US marine Paul Whelan and 14 others in its biggest prisoner swap with the West since the Cold War.
On Wednesday, an American man accused of violence against a Russian law enforcement officer in Moscow was sentenced to 15 days in custody for "hooliganism".
Karelina's employer, the Ciel Spa at the SLS Hotel in Beverly Hills, wrote on Facebook in February that she had been "wrongly accused".
Her partner has also publicly petitioned for her release.
Karelina was first detained on 27 January while visiting family in Yekaterinburg, almost a month after flying to Russia, according to a Russian rights group.
Russian regional news agency URA.RU reported the charge was related to "swearing in a public place", an accusation she rejected in court, according to the Mediazona news outlet.
FSB officers may have discovered she made the payment to the pro-Ukraine charity on her phone, but it was not clear how, according to Russian media outlets.
She was initially held for 14 days after being detained for "petty hooliganism" but was never released, as authorities charged her with "treason" while she was in custody.
Russia often arrests foreigners on minor charges before accusing them of more serious offences like treason or espionage.
