The Ukrainian military has released new footage of its devastating drone attack that left dozens of Vladimir Putin's irreplaceable nuclear bombers up in flames.

Ukraine's most daring attack of the war to date, dubbed Operation Spiderweb, saw more than 100 first-person view (FPV) kamikaze drones smuggled into Russia in wooden containers disguised as modular homes.

They were loaded onto civilian trucks and driven behind enemy lines by Russian lorry drivers seemingly unaware of what they were carrying.

The vehicles were parked within range of five airfields stretching from northern Russia down to Siberia, at which point the hidden roofs of the wooden cabins were opened remotely and the FPV drones took to the skies.

What happened next served as a devastating blow to Putin's forces, as 41 of his prized aircraft - worth some £1.5billion - were decimated in just a matter of minutes.
