Either Ukrainian jet-drones or cruise missiles struck the 75th Arsenal in Serpukhov, Moscow Oblast, resulting in a large fire breaking out. This facility is used to repair and store military equipment, including surface-to-air missiles for the Buk-M1, Buk-M2 and S-300V systems. Ukraine has been carrying out a large-scale long-range drone attack on Moscow Oblast for several hours tonight. So far, this is the only known impact site. The vast majority of drones were shot down as usual.
