US ballerina Ksenia Karelina freed in prisoner swap with Russia over treason conviction.

US-Russian dual citizen and ballerina Ksenia Karelina has been released from Russian prison in a prisoner exchange. Karelina was convicted of treason for donating about $52 to a charity aiding Ukraine. She was sentenced to 12 years in prison. In exchange, the US freed Arthur Petrov, a German-Russian citizen arrested in Cyprus for exporting sensitive technology to Russia. The swap took place in Abu Dhabi, brokered by the CIA.
