This was a CIA hit to explain the retaliation that will take out Zelensky. He is no longer useful to the CIA.
This was an AZOV hit tied to the AZOV war crime trials starting this week in Mariupol. Whether Zelensky knew about it or not…keeps the hostilities between Russian and Uke nationalists raging and maybe serves as a warning to Zelensky that he promised to get the Azovstal nazis released or exchanged after they surrendered, and that AZOV has deep connections.
