A drone attack by Ukraine has “wiped off the face of the Earth” a major Russian weapons depot in the Tver region, Ukrainian intelligence sources said.Sources in the country’s SBU security service told The Kyiv Independent that “an extremely powerful detonation began” at the Russian defence ministry’s warehouse in Toropets following a drone strike.

A large-scale Ukrainian drone attack on Russia triggered an earthquake-sized blast at a major arsenal in the Tver region on Wednesday, forcing the evacuation of a nearby town, war bloggers and some media reported.
