Four truck drivers accused of transporting explosives for a Ukrainian Security Service (SBU) drone attack on Russian military airfields have been released due to insufficient evidence. Andrei Merkuryev, Alexander Zaitsev, Mikhail Ryumin, and Sergey Kanurin were charged with terrorism and transporting explosives as part of an organized group.

The drivers were allegedly recruited by the SBU to transport explosives for a drone attack on Russian military airfields. They claim they were unaware of the cargo's nature and even assisted in downing some of the drones. The SBU operation, codenamed "Pautina," reportedly caused 2 billion rubles in damages.
