LONDON (Reuters) -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.

Unverified video and images on social media showed a huge ball of flame blasting into the night sky and multiple detonations thundering across a lake about 380 km (240 miles) west of Moscow.
