It will be recalled that there was an explosions in the Russian military town of Belgorod, just a few miles away from the border, but this incidents were not caused by shelling from the Ukrainian side.

Videos and images of the explosions and ensuing fire were shared extensively on Twitter and Telegram, alongside claims that it was caused by a rare counteroffensive strike by Ukrainian forces with an OTR-21 Tochka, or "Tochka-U," a Soviet-made tactical ballistic missile.

"Ukraine carried out a precision strike with the Tochka-U missile on an ammunition warehouse in the village of Oktyabrskoe, near Belgorod, Russia. Russia supplies its artillery attacking Ukraine with rockets and missiles stored at the facility," Yury Butusov, a Ukrainian journalist, wrote on Tuesday night on his Facebook page.

"Judging by the explosion and the distance of the warehouse, the 19th missile brigade of the Armed Forces of Ukraine has conducted an effective effort to demilitarize and denazify Russia," the military correspondent added, citing Ukrainian media sources.
