Ukraine says at least 40 Russian warplanes hit in massive drone strikes

Ukraine claims to have hit more than 40 Russian warplanes at several military airfields, in what appears to be one of the most audacious drone attacks so far on Russian aviation.

According to a statement from Ukraine's security service, SBU, "enemy strategic bombers are burning en masse in Russia".

The SBU said Ukraine is conducting "a large-scale special operation aimed at destroying enemy bomber aircraft."

Dramatic footage has emerged purportedly showing a drone attack at Belaya airbase in Irkutsk oblast, Siberia, thousands of miles from Ukraine.

Russia's military has not commented on the issue.
