In a significant prisoner exchange between the United States and Russia, Ksenia Karelina, a Russian-American ballet dancer who was imprisoned in Russia for allegedly committing treason related to a charity donation to Ukraine, has been released. The swap, which involved intelligence agencies from both countries, has been confirmed by U.S. officials, including Senator Marco Rubio. Karelina was sentenced to 12 years in prison but is now free as part of a broader negotiation that also returned other detainees to their respective countries. This development highlights the ongoing diplomatic efforts between Moscow and Washington amid tense relations.
