Ukraine: Law enforcement in Kharkiv has identified 25 collaborators of Russia who escaped to Europe after the start of the invasion and passed on their identities to Interpol.

As you may recall, the FSB used collaborators in Ukrainian law enforcement & military in an attempt to do a repeat of the Crimea invasion - where the proverbial gates to the city were left wide open.
They succeeded in Kherson, but failed in Kharkiv.
