A Ukrainian drone attack launched overnight succeeded in destroying an ammunition depot in the western Russian region of Tver, a source from Ukraine’s Security Service (SBU) told CNN on Wednesday.

A suspected Ukrainian drone attack at an ammunition depot in Russia's Tver region has been described on social media as possibly the biggest event of the war started by Vladimir Putin.

Specialists from the Institute for the Study of War (ISW) have discussed the Ukrainians' destruction of an ammunition depot in Tver Oblast, western Russia, which caused a minor earthquake. They believe this event will influence Russia's actions in Ukraine and significantly hinder their operations.
