Ukraine's main domestic security agency said on Friday it had uncovered a Russian spy network involving Ukrainian lawmaker Andriy Derkach who was previously accused by the United States of being a Russian agent.
The State Security Service (SBU) said Derkach, whose whereabouts were not made clear, set up a network of private security firms to use them to ease and support the entry of Russian units into cities during Moscow's Feb. 24 invasion.
