MQ-9 UAV was shot down by a Russian SU27 fighter jet recently. It was flying over international waters. It is unwise to attack a drone as it can be armed with air to air missiles. Apparenty a Russian fighter jet sprayed the MQ-9 with fuel and when that didn't stop it, they fired a cannon into the propeller. The MQ-9 crashed into the Black Sea.
I won't be surprised if Moscow tries to attack a NATO country next. It would be a shame if the Kremlin was demolished.
