Ukraine launches major drone attack on Russian bombers, security official says

Reported strikes on four airbases in Siberia mark escalation in cross-border incursions before planned peace talks

Ukraine has launched a large-scale" drone attack against Russian military bombers in Siberia, striking more than 40 warplanes thousands of miles from its own territory, a security official has said, after it smuggled the drones to the perimeter of the airfields hidden in the roofs of wooden sheds.

On the eve of peace talks, the drone attack on four separate airfields was part of a sharp ramping up of the three-year war, with Russia launching waves of drones at Ukraine, while Moscow said sabotage was to blame for two train derailments that left seven people dead.
