A Ukrainian drone attack caused a massive explosion at a Russian ammunition depot in the Tver region. The explosion was reported to be so powerful that it resembled the detonation of 200-240 tonnes of high explosives.

Ukraine has repeatedly targeted border regions such as Bryansk, Kursk and Belgorod. The attack on Tver, about 500 kilometers from the border, is not as common, but is an example of what Ukrainian officials have repeatedly said they want to do in order to hit Russian military infrastructure that could be used to attack Ukraine.
