Ukrainian drone attacks expose Russian air defences

A third Russian airfield was on fire on Tuesday (December 6) from a drone strike.

Russian media released footage of what they said was the aftermath of the alleged attack on the Kursk region airfield.

The governor said an oil storage tank there had been set ablaze but there were no casualties.

It comes a day after Ukraine demonstrated an apparent new ability to penetrate hundreds of miles deep into Russian air space with attacks on two Russia air bases.

And on Tuesday prompted Britain's defense ministry to say "If Russia assesses the incidents were deliberate, it will probably consider them as some of the most strategically significant failures of force protection since its invasion of Ukraine.

Russia confirmed it had been hit by what it said were Soviet-era drones at Engels air base.

600km from the nearest Ukrainian territory, Ukrainian presidential adviser Oleksiy Arestovych said it was the only base Russia has that is fully equipped for the giant bombers Russia has used in attacks on Ukraine's energy grid.
