Footage appearing to showing the aftermath of an attack on a Russian military convoy near the town of Rylsk in Russia’s southwestern Kursk region appeared on social networks overnight, in which 14 military trucks that had been carrying Russian servicemen can be seen in various states of destruction.

Ukrainian OSINT project CyberBoroshno confirmed the exact location of the incident as “the village of Oktyabrskoye in the Rylsk district of the Kursk region, eight kilometres from Rylsk.”

“Judging by the look of the column, about half of the troops were killed,” military analyst Yan Matveyev said, adding that he thought an entire battalion had been destroyed in what he called “one of the bloodiest and most massive strikes in the entire war” to date.

Matveev said that the carnage was most likely the result of a High Mobility Artillery Rocket System (HIMARS) missile strike.

Multiple pro-war Russian bloggers have confirmed that a Russian convoy in the Kursk region was struck.
