Ukraine carries out largest drone attack yet on Russian airbases, Kyiv source says

KYIV (Reuters) - Ukraine has carried out its largest drone attack yet on four Russian military airfields, a Ukrainian security source told Reuters on Wednesday.

The attack was aimed at undermining Russia's ability to use warplanes for gliding bomb attacks, the Ukrainian security source added.

Reuters could not immediately independently verify the claim.
