Russia demanded the extradition of a Russian convicted for the 2019 Tiergarten murder in Berlin as a condition for a prisoner swap with the US on July 2022; the US rejected the demand.
In July 2022, Russia reportedly demanded the extradition of Vadim K., a Russian national serving a life sentence in Germany for the 2019 Tiergarten murder in Berlin, as a condition to release two US citizens detained in Russia. The demand was conveyed via informal intelligence channels at the start of July but was considered problematic by involved parties. The US firmly rejected the demand, declaring it an unacceptable attempt to deflect from a serious US proposal to exchange detained persons, including Russian arms dealer Viktor But imprisoned in the US. The case of Vadim K., convicted in December 2021 for killing a Georgian man on behalf of Russian state actors, has caused diplomatic tensions between Germany and Russia, with mutual expulsions of diplomats. The US is also negotiating for release of basketball player Brittney Griner and former soldier Paul Whelan from Russian detention. The prisoner swap negotiations involved US Secretary of State Antony Blinken and Russian Foreign Minister Sergei Lavrov.
Confidence: High
The article clearly describes Russian state demand to extradite a convicted agent as part of a prisoner swap, which is a coercive diplomatic tool and abuse of diplomatic channels with hostile intent. The US rejection confirms the adversarial nature.
