Kyiv SBU drone strike likely relay-guided from within 5 km, advisor claims

A drone struck the SBU building in central Kyiv on September 4; an unofficial presidential advisor alleges it was controlled via a relay activated by a Russian agent within 5 km, implying a local network rather than long-range control. The claim is unverified and based on one advisor's assessment, but if true it signals an elevated insider threat in the capital.
