Dramatic new footage recorded by Ukrainian attack drones has laid bare the devastation they inflicted on Russian airbases during Operation Spiderweb.

The covert mission - overseen in secret by Ukrainian President Volodymyr Zelensky and hailed as one of Kyiv's biggest wartime achievements - used hundreds of first-person view (FPV) drones to strike at the heart of Moscow's air force.

The state-of-the-art weapons were smuggled into Russia in wooden containers on the back of lorries, with the deadly cargo disguised as modular homes and transported by unsuspecting Russian drivers.

The vehicles were parked near strategic airbases before their roofs opened remotely, unleashing swarms of drones that targeted and destroyed bombers on the ground.

The strikes took place on Sunday, with footage released today showing flames engulfing aircraft at four military airfields - Olenya in the Arctic region of Murmansk; Dyagilevo in western Russia; Ivanovo, northeast of Moscow; and Podmoskovye in Moscow.
